Abstract
In this work, a method to generate a pulse train based on the strictly negative nonlinear phase shift during the amplification of a dynamic signal in a semiconductor optical amplifier (SOA) in association with frequency filtering is proposed. A 40 ps width pulse train with a huge continuous tunability repetition frequency ranging from 1 MHz to 5 GHz was experimentally demonstrated. The pulse train properties were characterized by methods such as duty cycle tailoring, and SOA injection current variation.
