摘要

深空探索将需要在成本、尺寸、重量和功率方面进行优化的激光通信系统。为了改善这些参数，本课题组开发了一种基于磷化铟的光子集成电路，用于光脉冲位置调制(PPM)。现场可编程门阵列(FPGA)被编程为PIC的专用驱动程序。FPGA能够产生2- 4096-ary的PPM，插槽时钟速率高达700 MHz。

Deep space laser communication hardware driver (Conference Presentation)

Deep space exploration will require laser communication systems optimized for cost, size, weight, and power. To improve these parameters, our group has been developing a photonic integrated circuit (PIC) based on indium phosphide for optical pulse position modulation (PPM). A field-programmable gate array (FPGA) was programmed to serve as a dedicated driver for the PIC. The FPGA is capable of generating 2-ary to 4096-ary PPM with a slot clock rate up to 700 MHz.
