两段式1.55-/spl μ m量子阱DFB激光器，kappa高达300/cm，在80 GHz的记录频率下表现出自脉动。实现了极宽，连续的电频率调谐范围，从12-64 GHz。目前的自脉动机制属于跳动型振荡。这种效应锁定到一个光注入调制信号被验证。>
Two-section, 1.55-/spl mu/m quantum-well DFB lasers, with a very high kappa of 300/cm, show self-pulsation at a record frequency of 80 GHz. An extremely wide, continuous, electrical frequency tuning range, from 12-64 GHz, is achieved. The present self-pulsation mechanism is assigned to a beating type oscillation. Locking of this effect to an optically injected modulated signal is verified. >
