Abstract

Fast bistable wavelength switching between two longitudinal modes separated by 1.7 nm was achieved in a two-electrode distributed feedback laser with inhomogeneous excitation. As a result, a fast wavelength switching time less than 200 ps was observed in this device. In addition, high-speed repetitive wavelength switching operation up to 1 GHz was achieved. This indicates that the device is capable of repetitive wavelength switching within 1 ns, including delay time and rise time.<>
