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.
我们报道了一种新型单腔双波长激光器,其在增益区两侧各有两个分布式布拉格反射(DBR)光栅,用于太赫兹通信应用。通过改变其中一个DBR光栅的注入电流,可对激光器的光拍频进行广泛调谐。在该器件中,还集成了一个高速电吸收调制器(EAM),可用于高达25 Gb/s的数据调制。
