We report a novel single-cavity dual-wavelength laser that has two distributed Bragg reflector (DBR) gratings at each side of a gain section for THz communication applications. By varying the inject current of one of the DBR gratings, the optical beat frequency of the laser can be widely tuned. In the device, a high-speed electro-absorption modulator (EAM) is also integrated and can be used for up to 25 Gb/s data modulation.

集成了高速EAM的双波长DBR激光器,用于THz通信

我们报告了一种新颖的单腔双波长激光器,该激光器在THz通信应用的增益部分的每一侧都有两个分布式布拉格反射器(DBR)光栅。通过改变其中一个DBR光栅的注入电流,可以广泛地调节激光器的光学拍频。在该设备中,还集成了高速电吸收调制器(EAM),可用于高达25 Gb / s的数据调制。
