12^th International Conference on Optics, Photonics & Lasers June 17-18, 2019 London, UK

This is the technology which generates light and harnesses other radiant energy that is having their quantum unit as photon. These are source of energy which shows best properties. These are being used in almost every activity which is present in the present date which is medicine, science, agriculture, information, industry and entertainment and many more. They always give a successful output.

Photonics is the study which involves the usage of radiant light. The fundamental element of this technology is photon. In these applications they use the photon in the same way that electronic devices use the electron. Therefore, the devices which are running on light have more advantages than the devices which are running on the electricity because light travels 10 times faster than the electricity.

These fibre optics are mainly used to carry larger information from one place to another place such that the loss of the information is very less when compared to the ordinary electrical cables because fibres are being uses rather than metals. In this case the fibres don’t get any kind of effect from the electromagnetic interferences whereas metals do. These fibres are usually made of silica glass or plastic which have diameter less than the diameter of human hair. These fibres are also used for illumination purpose and imaging especially in the case of aerospace

SES is the technique which involves a reaction of chemical interactions and enormous electromagnetic fields near a surface. It is very sensitive as well as selective and has been exploited in physics, chemistry and biology and medicine. This method is one of the most enormously developing and important technique in the present world. In this method they use Nano sized roughened metal surfaces which are basically made of silver and gold. When these metals made to get excited under the presence of laser, their surface charges get drive thus creating a highly localised light field (plasmonic).

These are the optics which belong to the branch of optics and photonics which uses light controlling components to get the images of the celestial objects in the space. The perfect example for this would be a telescope. Astronomical optics has a combination of well machined lenses and mirrors in order to reduce any image distortion and sensitive sensors to detect low levels of light.

The beginning of the new era with the use of electromagnetic waves for the long distance communications using radios is all about optical technology. The radio waves are longer than the light waves. This whole newly established technology brought some of the main fascinating technologies in to the world. The older mechanical methods were made outdated and the use of these electronics came into existence, which were faster than the previous methods.

It is the study of phenomenon which takes place as the consequence of the changes in the optical properties of a material system in the presence of light. Nonlinearity is typically observed at high intensities (for example those which are generated by lasers). Nonlinear optics provides the key technologies which helps in providing radiation sources in various wavelength ranges from x-rays to terahertz. These are basically used in combination with laser technology.

The study and working of electronic devices or systems that source, detect and control light, with a sub-field called photonics is known as Optoelectronics. This is type of system in which the light includes invisible radiations such as infrared, UV, X-rays and Gamma rays along with invisible light. This is the type of device which has got electrical-to-optical or optical-to-electrical transducers. 

This quantum science is all about the study of Nano particles so that the properties of these naturally found Nano materials are being implemented on the synthetic materials which are being processed in the laboratories these days. The synthesised materials could be formed with the properties like high strength, resistance to water, heat and dust particles.

Lasers are something which can do several works such as reshaping corneas, pulverizing gallstones, killing tumours and reaming arteries and many more. These are some of the techniques which are being employed in today’s medicinal world where lasers are being used to diagnose patients and the applications of lasers to biology and medicines has been increasing day by day.

The term photonics was first developed as an outgrowth of the practical semiconductor light emitters. It is the science which belongs to physical science department which gives the idea of light (photon) generation, detection and manipulation through various processes like transmission, emission, signal processing, modulation, amplification, switching and sensing.

The fibre laser technology is a technology where the fibre laser uses the optical fibre as the active medium which is been doped with the rare earth elements like neodymium, holmium, yttrium, thulium, erbium, and praseodymium. One should not have to be worried about the type of earth metal which is being used, the only thing which as to be remembered is that the fibre is being used at the centre.

Optics in many manufacturing units is being acting as the main source of increasing the capabilities of current manufacturing processes and has made the new ones to exist. Optics has made everything easy and fast. For instance we can consider light which is being used to process materials remotely even in the harsh environments and vacuum conditions of the manufacturing unit. Even with the use of optics the contamination of the process by the probe beam and the tear and wear of the tools is being reduced without having any sought of surface contact.

This is a device that makes the atoms and molecules to stimulate in such a way that they start emitting light of a particular wavelength and amplifies that light which is further made to produce a narrow beam of light or radiation. The process of emission generally covers many types of lights with different wavelengths those are visible, infrared, and ultraviolet. Depending upon the wavelength or the type of light laser systems is developed.

Optical Communication and Networking is the process in which the data or message is being transmitted from the transmitter to the receiver. In which the information would transmitted among various telecommunication networks. These systems can operate in a LAN and in a WAN which is almost equivalent to a metropolitan and regions which may consists of regional, national, international distances.

This is the study which involves the applications of quantum mechanics on the process which involves the light (or photons in other words) and its interactions with the matter. To understand the behaviour of electromagnetic waves there has to be a study of individual photons. This means that the whole field of quantum physics mainly focuses on the study of individual photons.
