Ultralow chirp and high-speed 1.55 mu m multiquantum well lambda /4-shifted DFB lasers

An ultra-low-chirp, high-speed, 1.55- mu m, multi-quantum-well (MQW), lambda /4-shifted, InGaAsP distributed-feedback (DFB) laser is demonstrated. A record chirp width of 0.4-0.5 nm (20-dB down full width) is achieved at 10-Gb/s direct modulation. This low-chirp single-longitudinal-mode operation is attained by an increase in the quantum size effect in the MQW active layer.<<ETX>>
