Abstract

Active mode-locking of semiconductor lasers1,2 is the most promising technique for generating the electrical-clock-driven short-optical-pulses required in ultra-high bit rate soliton transmission and optical signal processing. The pulse width tunability is an important factor in these application fields, because a prescribed duty factor is necessary at a given clock frequency. The multiple-quantum-well electroabsorption optical modulator (MQW-EAM) utilizing quantum-confined Stark effect has a fast nonlinear response to applied voltage and can gate lightwaves with a variable duty factor only with sinusoidal driving voltage.
