Performance Analysis of SMQW SOA Based On Optical Confinement Factor

Nipu R. Barai, Rinku Basak

Study of the dependency of optical confinement factor (OCF) on the structure parameters of symmetrical multiple quantum well (SMQW) semiconductor optical amplifier (SOA) is important for better design of SOA devices. This paper presentsan overall structure of a SMQWSOA, and dependency analysis of OCF on different structure parameters.The effects of number of well layers, well thickness and barrier thickness of SMQW SOA on OCF are investigated through simulations performed using MATLAB.The simulation results show that OCF of a SMQW SOA increases with increasing number of quantum well layers and well layer thickness. However, the change in barrier thickness doesn‟t have significant impact on the OCF.Thesimulation resultsalso indicate that with appropriate number of well layers and well layer thickness, it is possible to obtain a better OCF.The findings of this study can be used for creating more efficient and stable SMQW SOA design.
