AbstractThe optical fiber communication offers a huge bandwidth for data transmission at higher data rates but to increase the throughput for long-haul networks, metro data links, and data centers, additional fiber is required which is not economical. For effective reception of signals at the receiver, the photo detector in optical communication requires higher efficiency, lower noise, ultrafast response and optimum received signal strength. The inherent dispersion and nonlinear impairments in optical fiber communication system can be overcome by using the Fiber Bragg Grating (FBG) which is a Dispersion Compensating Module. FBG helps to improve the long-haul transmission by providing an efficient system performance. This paper presents a detailed review of FBG and photo detectors and their use in an Optical communication system. This paper will help the researchers to find useful material at a single platform.

The transverse asymmetry of the index modulation profile in the asymmetric few-mode fiber Bragg grating (FM-FBG) was investigated. The transverse asymmetry of the index modulation profile will lead to mode conversion between modes with the different azimuthal orders, and this asymmetry is characterized by the attenuation coefficient α. We evaluated that the value of attenuation coefficient α was 0.2 μm−1, and grating amplitude χ was 2.8 × 10−4 for FM-FBG inscribed by UV single-side illumination. We found that the optimized value of α was 0.16 μm−1, at which the maximum mode conversion efficiency of LP01–LP11 can be achieved. The results of this paper provide great potential application in few-mode fiber (FMF) devices and mode division multiplexing (MDM) optical communication.
