Optimisation of optical bandpass filters for semiconductor optical amplifier-based all-optical wavelength conversion using genetic algorithms

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review

Abstract

We use genetic algorithms to numerically optimise optical bandpass filters for non-inverted wavelength conversion based on semiconductor optical amplifiers. Output signal eye openings greater than 30 dB are obtained using a Hermite-Gaussian sum series to describe the filter’s amplitude transfer function. We show that this can be implemented experimentally using an asymmetric Mach-Zehnder interferometer combined with a Gaussian optical bandpass filter. Finally, we explore the possibility of using a Sech-Hermite sum series to describe the filter and compare the results with those obtained for the Hermite-Gaussian filter.
