Classical optics is divided into two main branches: geometrical (or ray) optics and physical (or wave) optics. In geometrical optics, light is considered to travel in straight lines, while in physical optics, light is considered as an electromagnetic wave. Physical optics  is the study of the wave properties of light, which may be roughly grouped into three categories: interference, diffraction, and polarization And In  Physical optics, light is considered to propagate as a wave. This model predicts phenomena such as interference and diffraction which are not explained by geometric optics. The speed of light waves in air is approximately 3.0×108 m/s (exactly 299,792,458 m/s in vacuum).

Optical Imaging is the method in which light is being used to get the investigational imaging of the medical operations. Basically, optical imaging is of two types which are diffusive Imaging systems and ballistic imaging system. Some of the main examples are scanning laser ophthalmoscopy, optical coherence tomography, optical microscopy and endoscopy, spectroscopy.

Nano-optics is the study of optical phenomena and techniques on the manometer scale, that is, near or beyond the diffraction limit of light. It is an emerging field of study, motivated by the rapid advance of Nano science and nanotechnology which require adequate tools and strategies for fabrication, manipulation and characterization at this scale. In Principles of Nano-Optics the authors provide a comprehensive overview of the theoretical and experimental concepts necessary to understand and work in nano-optics. With a very broad perspective, they cover optical phenomena relevant to the nanoscale across diverse areas ranging from quantum optics to biophysics, introducing and extensively describing all of the significant methods.

Photonics is an area of study that involves the use of radiant energy (such as light), whose fundamental element is the photon. Photonic applications use the photon in the same way that electronic applications use the electron. Devices that run on light have a number of advantages over those that use electricity. Applications of photonics: Applications of photonics are ubiquitous. Included are all areas from everyday life to the most advanced science, e.g. light detection, telecommunications, information processing, photonic computing, lighting, metrology, spectroscopy, holography, medicine (surgery, vision correction, endoscopy, health monitoring), bio photonics, military technology, laser material processing, art diagnostics (involving InfraRed , Reflectography, Xrays, UltraViolet fluorescence, XRF), agriculture, and robotics.

Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometric optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. Three basic laws: The law of rectilinear propagation (transmission). ... When a ray of light is reflected at an interface dividing two optical media, the reflected ray remains within the plane of incidence, and the angle of reflection θ r equals the angle of incidence θ i.

Basic Principle of Interferometer: Interferometer is a precise instrument for flow visualization. The variation of refractive index of the flowing gas with density is the basic principle used in these  system. The principle of interference of light waves is used.

  • Operation of Interferometer: Light rays from a source are collimated with a lens L1. That is, the light rays become a parallel beam of rays when they come out of the lens L1.
  • This collimated light rays are then split by a beam splitter B1. The two beams traverse at right angles to each other.
  • That is the beam

Laser medicine consists in the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, photo rejuvenation, and laser surgery. While the history of laser begins in 1951, the first medical application is reported by Goldman in 1962. In cardiovascular surgery McGuff first used a Ruby-Laser in 1963 for the experimental ablation of atherosclerotic plaques. After a long time of investigations and new developments in laser technology first clinical applications were performed by Choy and Ginsburg in 1983. Since that time the effectiveness of laser angioplasty in coronary and peripheral vessel is investigated in several clinical trials and first results are encouraging, so that laser is about to find its place in the treatment of cardiovascular diseases too.

Light, like radio, consists of electromagnetic waves. The major difference between the two is that light waves are much shorter than radio waves. The use of electromagnetic waves for long-distance communications was the beginning of an industry known first as wireless and later as radio. This industry was the foundation for electronics, which brought the world so many fascinating technologies.

Laser based 3D scanners use a process called trigonometric triangulation to accurately capture a 3D shape as millions of points. Laser scanners work by projecting a laser line or multiple lines onto an object and then capturing its reflection with a single sensor or multiple sensors.

Types of 3D Scanners and 3D Scanning Technologies:

  1. Short Range 3D Scanners Short Range 3D scanners typically utilize a Laser triangulation or Structured Light technology.
  2. Laser based 3D Scanners Laser based 3D scanners use a process called trigonometric triangulation to accurately capture a 3D shape as millions of points. Laser scanners work by projecting a laser line or multiple lines onto an object and then capturing its reflection with a single sensor or multiple sensors.

Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. The silicon is usually patterned with sub-micrometre precision, into microphotonic components. These operate in the infrared, most commonly at the 1.55 micrometre wavelength used by most fiber optic telecommunication systems Fields within organic photonics include the liquid organic dye laser and solid-state organic dye lasers. Materials used in solid-state dye lasers include.

Advantages: Its great advantage is that it can be manufactured just like normal computer chips but with patterned silicon to transmit data-carrying laser signals. Able to carry more data while consuming less power and without heating up or causing any degradation in signal, silicon photonics will disrupt a range of technologies.

Process automation is today in the largest demand on the industrial market, which must meet very high production requirements and adapt to an increasingly aggressive competitiveness, in which time often plays a fundamental role. The most important consequence of this is the search for high performance tools and technologies that can adapt to different needs. When we speak of efficiency and flexibility in the world of Laser Marking and its infinite applications, we certainly place fiber lasers in first place. In today's market, these are by far the most used in companies that use this technology.

Photonic crystals are periodic dielectric structures that are designed to form the energy band structure for photons, which either allows or forbids the propagation of electromagnetic waves of certain frequency ranges, making them ideal for light-harvesting applications (Maka et al., 2003).

Applications:  Photonic crystals are attractive optical materials for controlling and manipulating light flow. One dimensional photonic crystal is already in widespread use, in the form of thin-film optics, with applications from low and high reflection coatings on lenses and mirrors to colour changing paints.

Materials, structures, phenomena and devices that are still in an investigative stage, or that are not yet targeting specific application requirements. Novel materials and material combinations and structures that are enabling new functions or science, and nanophotonic structures. Potential examples include (not limited to) low dimensional structures, amorphous or disordered materials, graphene, complex oxides, photonic crystals, antennas, gratings, subwavelength structures, and plasmonics and their hybrids.


An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material that is normally silicon. The integration of large numbers of tiny MOS transistors into a small chip results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block approach to circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones, and other digital home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs.

The subcommittee on Semiconductor Lasers solicits papers on recent advances in the design, fabrication, and characterization of laser sources based on carrier injection in semiconductor materials.

The word LASER stands for Light Amplification by Stimulated Emission of Radiation. A laser is a device that emits a concentrated beam of photons, which are the basic units of electromagnetic radiation. The applications of laser radiation in the nanotechnology are ranging from fabrication, melting and evaporating. The combination of laser and nanotechnology in the field of cancer treatment has made a good progress over the year.

The subcommittee on photonic materials science and technology solicits papers in all aspects of photonic materials, including materials science and technology, material growth and synthesis, heterogeneous integration, material characterization, and integration architectures.
