Abstract

A configuration of semiconductor fiber ring laser (SFRL) is used to achieve a tunable all-optical logic NOR gate at 20 Gb/s. Both gain and gain modulation is provided by a single semiconductor optical amplifier (SOA) in the ring cavity. In the theoretical simulations, sectional model is used for SOA and iterative condition is used for ring cavity to simulate the output from SFRL. All-optical NOR operation is successfully demonstrated experimentally at 20 Gb/s. There is a good agreement between theoretical simulations and experimental results. The extinction ratio higher than 14.9 dB is obtained as the output wavelength is tuned from 1530nm to 1560nm.
