应用于星间光通信系统的光发送机的设计

根据自由空间光通信的特点，在理论分析和数值仿真的基础上提出了适用于星间光通信的长滤长光发送机方案，针对星间光通信对误码率的要求分析了大信号、高泵浦功率条件下ＥＤＦＡ中放大的自发辐射（ＡＳＥ）对系统信噪比增益的影响并通过计算给出了在ＯＯＫ调制方式下光发送机天线口径的最优范围。

Design of the optical transmitter in inter-satellite communication

According to the characteristic of free space optical communication, and on the basis of theoretical analysis and numerical emulation, we bring forward a design of long wavelength optical transmitter applied to inter satellite optical communication. We analyze the influency of the amplified spontaneous emission on the gain of SNR under the high power signal and pump condition and calculate the optimized caliber of the optical antenna with the OOK modulation on the basis of the requirement to the BER of the inter satellite optical communication system.
