Abstract
Introduction: Microwave photonics (MWP) is an interdisciplinary scientific and technological field that combines the microwave electronics and photonics worlds [1-3]. Emerging applications for information and communication networks (ICN) of fiber-wireless architecture, sub-terahertz wireless systems, radars, and electronic warfare systems indicate that MWP is set to be a subject of increasing importance. In a typical arrangement of MWP-based radio-frequency receiver, a photonic circuit is inserted between two microwave electronic chains (Fig. 1). For direct and inverse transfers of microwave and optical signals there are two interfacing units at their bounds: electrical-to-optical (E/O) and optical-to-electrical (O/E) converters. Between the interfaces there are various photonics units for processing microwave signals in optical domain.
Statement of the Problem: The developer of new MWP devices and systems is facing a problem of choosing an appropriate computer tool for their modeling and design, but is forced to use means of several computer-aided design (CAD) tools because the existing optical and optoelectronic CAD tools (OE-CAD) are not as developed as compared with the CAD tools intended for modeling of microwave devices (E-CAD) For example, well-known OE-CAD allows executing in precision manner the modeling of a fiber-optic link with detailed study of optical units’ characteristics, but RF and especially microwave and millimeter-wave functional units are represented without paying attention to specialties of microwave band. On the other hand, operating at symbolic level modern high-power microwave E-CAD tool simply and with high precision solves this problem but there are completely no models of active optoelectronic components in the libraries [4, 5].
In the paper, a number of the E-CAD models for active and passive MWP elements, such as semiconductor laser, photodetector, optical modulator, multichannel reflecting Bragg grating, and for some MWP devices are presented and experimentally validated.
