The Design and Simulation of Optical Receivers with Capability of AGC, Based on ZnO Crystal Structures using TMM Method

Reza Khodadadi; Samaneh Khodadadi

To recognize a ray in the wavelength range of 625 nm to 645 nm with the possibility of AGC (Automatic Gain Control), the conditions have been predicted in a way that using a structure of 21 pairs of crystal layers containing the mixture of oxide and glass with the failure coefficents nZnO = 2.0041, nGlass = 1.45 with a pair of air gap layers, the simulation can be carried out. In this optical receiver sensor, the length of channels is 100 nm and the analysis is based on TMM. At particular angles which the gain is more than 70% and the bandwidth is about 1 nm, the incident ray is acceptable and the system output is active; otherwise, the controller will change the direction of the incident angle to the closest one.
