Comprehensive Investigation Modeling For Semiconductor Optical Amplifier (SOA)

Esra Abdullah Alqudah, Aser Mohammed Matarneh.

Abstract
This paper presents the effects of the input signal on the gain and carrier density response of a semiconductor optical amplifier (SOA). The SOA is modeled using a segmentation method. The input bias current, input power, wavelength and the length of SOA required for amplification and switching functions are investigated. Moreover, the effect of the temperature on SOA operation is investigated as well as the thermo-optical effect. The operation principle is simulated and the results show the input boundary conditions and requirements in which the SOA can be used as an amplifier and as switch.

Key words: Semiconductor optical amplifier (SOA), carrier density, stimulated emission, gain response, thermo-optical effect, dynamic range, phase shift, linear region.
