Effect of Semiconductor Optical Amplifiers Types on Multiwavelength Fiber Laser Performance

Abstract

This paper demonstrates a multiwavelength fiber laser (MWFL) using different types of semiconductor optical amplifiers (SOAs) in conjunction with Lyot filter as comb filter. Three different SOAs were compared; linear, non-linear and booster optical amplifier (BOA). The multiwavelength generation using BOA had produced the best performance with extinction ratio (ER) of 52dB and peak power of −13.2dBm.
