A novel method of the performance analysis of SOA-assisted nonlinear optical-loop-mirror-based wavelength converter

摘要

Nonlinear Optical Loop Mirror (NOLM) is a very popular optical fiber device. When it's inserted semiconductor optical amplifier (SOA), a lot of use it can be provided with. This work assesses the prospects for high-speed all optical wavelength conversion using semiconductor optical amplifiers inserted in NOLM based on cross-phase modulation (XPM) in a SOA and interference in Sagnac Interferometer. In this paper, we analyzed of parameters optimization for XPM wavelength conversion in the structure mentioned above, Segmented model for SOA, additional continuous control pulse are exploited in the theoretical analysis. The influence of an additional input light on converted waveform is shown. The output power and extinction ration changing with signal wavelength and input power are introduced.
