研究了GaInAsP横向电流注入(LCI)激光器的发光和检测特性，以验证其作为光电功能器件的可行性。LCI激光器可以在准平面结构的半绝缘衬底上制备，非常适合与电子器件集成，是一种很有前途的光电集成电路(OEIC)光源。在发光特性方面，LCI激光器具有2 GHz以上的调制带宽。此外，在伪随机比特流输入信号的眼图中，确认了激光器在1-Gb/S信号下的良好睁眼。在光探测特性方面，3分贝探测带宽大于2 GHz，响应率为0.54A/W，偏振相关系数为0.17分贝。这些性能表明，LCI激光器可能是未来光电集成器件中发光和检测二极管的一个很好的候选者。
The light emission and detection characteristics of a GaInAsP lateral current injection (LCI) laser were studied to examine feasibility for optoelectronic functional devices. LCI lasers which can be fabricated on semi-insulating substrates in quasi-planar structures are very appropriate for integration with electronic devices, and are promising light sources for optoelectronic integrated circuits (OEICs). For the light emission characteristics, the LCI laser has a modulation bandwidth above 2 GHz. Also, good eye openings at 1-Gb/s signals is confirmed for the laser in eye diagrams for pseudorandom bit stream input signals. For the light detection characteristics, the 3-dB detection bandwidth of more than 2 GHz, high responsivity of 0.54 A/W, and small polarization dependence of 0.17 dB are confirmed. These performances show that the LCI laser might be a good candidate for the light emission and detection diode in OEICs in future.
