Abstract :
Tunable semiconductor lasers[1-3] are expected to play a major roll in both high-speed direct detection wavelength-division-multiplexed (WDM) systems and coherent heterodyne detection systems. Here we describe the structure and properties of multi-section tunable dynamic-single mode multiple-quantum-well (MQW) distributed-Bragg-reflector (DBR) lasers operating at 1.5 μm. These lasers display how threshold, excellent differential quantum efficiency, large tuning range, with both low chirp under high-speed direct modulation and narrow linewidth under CW operation.
