双电极锥形激光器使用单独的激励，以小的输入电流摆幅实现高输出调制深度，可与现有的标准光通信组件提供，使其成为一种新型的光无线通信源。提出了一种采用高功率、高调制效率双电极锥形激光器、传输距离为60 m、传输速率为1.25 Gbit/s的自由空间光无线通信系统。该系统的功率损失为6.5 dB。
A two-electrode tapered laser uses a separate excitation to achieve high output modulation depth with a small input current swing that can be provided with existing standard optical communication components, making it a novel source for optical wireless communications. Presented is a 1.25 Gbit/s free-space optical wireless communication system over a distance of 60 m, with a high power and high modulation efficiency two-electrode tapered laser. The system exhibits a 6.5 dB power penalty.
