复合腔激光二极管以基本往返频率的谐波进行锁模，以实现高达2.1太赫兹的重复频率。该器件由波长为860 nm的GaAs/AlGaAs材料制成，包括两个增益区和一个可饱和吸收体区，增益区之间有一个刻蚀槽反射器。自相关研究被用来研究不同反射器类型和反射率的器件行为。这些激光器可能会在太赫兹成像、医学、超快光纤链路和大气传感中得到应用。(C)2001年美国物理研究所。
Compound-cavity laser diodes are mode locked at a harmonic of the fundamental round-trip frequency to achieve repetition rates of up to 2.1 THz. The devices are fabricated from GaAs/AlGaAs material at a wavelength of 860 nm and incorporate two gain sections with an etched slot reflector between them, and a saturable absorber section. Autocorrelation studies are used to investigate device behavior for different reflector types and reflectivity. These lasers may find applications in terahertz imaging, medicine, ultrafast optical links, and atmospheric sensing. (C) 2001 American Institute of Physics.
