描述了一种用于产生短脉冲的单片集成光子器件的特性，该器件由锁模激光二极管、马赫-曾德尔调制器(MZM)和半导体光放大器(SOA)组成。为了便于设计、测试和制造，该集成器件被设计用于通过通用铸造方案来制造。以从14 GHz到109 MHz的电子可切换的重复频率产生6.8 ps脉冲的序列。利用单模通信光纤进行色散补偿，可将峰值功率提高7.4dB，脉冲可压缩至2.4ps。
We describe the characterization of a monolithically integrated photonic device for short pulse generation featuring a mode-locked laser diode, a Mach-Zehnder modulator (MZM), and a semiconductor optical amplifier (SOA). The integrated device is designed for fabrication by a generic foundry scheme with a view to ease of design, testing, and manufacture. Trains of 6.8 ps pulses are generated at repetition rates that are electronically switchable from 14 GHz to 109 MHz. The SOA boosts the peak power by 7.4 dB, and the pulses are compressible to 2.4 ps by dispersion compensation using single-mode telecommunications fiber.
