Effect of Noise on Optical Frequency Comb

Abstract

In this thesis work, we study the effect of noise on the optical frequency comb. We consider a microresonator system made of a vertical surface-emitting laser with a graphene saturable absorber. The investigation is done by solving the complex Ginzburg-Landau equation that represents the microresonator system. The split-step Fourier method-based code is used to solve the governing equation and to get the optical frequency comb. The different range of optical frequency comb is identified. Different sets of optical frequency comb are observed for the different ranges of the signal-to-noise ratio. We study how the optical frequency comb changes with a change in the operating wavelength. These results may help in the enhancement of the performance of optical frequency comb.
