Abstract

We develop an analytical expression for the output polarizer placement angle of a semiconductor optical amplifier (SOA)-based power equalizer in terms of the input polarizer angle and further investigate the relationship between the magnitudes of output power, input power, and input polarizer angle. We have taken into consideration time-dependence of the output power from the SOA and numerical simulation results have been provided to illustrate the concept using typical values.
