摘要
单向运动载流子光二极管(UTC-PD)具有高速和大电流的特点,与RTD相结合可构成一高速光控MOBILE,能够应用于80Gb/s的光纤通信、光信息处理和高速光网络中。在详细介绍UTC-PD的基础上,讨论了RTD/UTC-PD光控MOBILE的工作原理、材料结构和制作工艺、电路性能测量等,并进一步将上述结果推广到交流信号情况下RTD/UTC-PD光控MOBILE的瞬态特性。结果表明,存在三个因素影响该单元电路的工作速度,即交流电流效应、开关延迟时间和UTC-PD器件的带宽。
The uni-traveling-carrier photo-diode （UTC-PD） is a new photo-diode that has both the high speed and the large current density. The UTC-PD with RTD can form a high speed photo-controlled MOBILE which used in 80 Gb/s optical fiber communication, optical informa- tion processing and high speed optical network. The operating principle, the material structure and processing, the measurement of circuit performances of the RTD/UTC-PD photo-controlled MOBILE were discussed. Furthermore, all of these could be extended to the situation of tran- sient characteristics for the AC signal. The result shows that the AC current effect, the delay time of switching and the bandwidth of UTC-PD device affect the operating speed of RTD/UTC- PD MOBILE.
