在这里，我们提出、制作并表征了InGaN多量子阱发光二极管（MQW-LED）、波导和InGaN mqw光电探测器在单芯片上的悬浮光子集成。InGaN MQW-LED独特的发光特性使得利用可见光建立多维空间数据传输成为可能。平面内光通信系统由InGaN MQW-LED、波导和InGaN mqw光电探测器组成，通过商用光电二极管模块检测自由空间光发射来实现面外数据传输。此外，当两个InGaN mqw二极管同时在光发射和检测模式下工作时，实验证明了全双工光通信的数据传输速率为50 Mbps。通过自干扰对消方法提取面内叠加信号，根据提取的发射信号计算得到的面外叠加信号与计算得到的信号吻合较好。这些结果为片上InGaN光子集成的发展提供了广阔的前景。(C) 2017 Elsevier B.V.版权所有
Here, we propose, fabricate and characterize suspended photonic integration of InGaN multiple quantum -well light-emitting diode (MQW-LED), waveguide and InGaN MQW-photodetector on a single chip. The unique light emission property of InGaN MQW-LED makes it feasible to establish multidimensional spatial data transmission using visible light. The in-plane light communication system is comprised of InGaN MQW-LED, waveguide and InGaN MQW-photodetector, and the out-of-plane data transmission is realized by detecting the free-space light emission via a commercial photodiode module. Moreover, a full-duplex light communication is experimentally demonstrated at a data transmission rate of 50 Mbps when both InGaN MQW-diodes operate under simultaneous light emission and detection mode. The in-plane superimposed signals are able to be extracted through the self-interference cancellation method, and the out-of-plane superimposed signals are in good agreement with the calculated signals according to the extracted transmitted signals. These results are promising for the development of on-chip InGaN photonic integration for diverse applications. (C) 2017 Elsevier B.V. All rights reserved.
