摘要
微光学元件在现代光学中具有重要的作用,通过制作8台阶的微闪耀光栅列阵,控制周期参数,利用其在空间的闪耀输出与级连,可以实现2×2、4×4以及8×8的光开关功能,光信号交换透明,无光电-电光转换过程。对微闪耀光栅输出信号的串扰分析表明,微闪耀光栅光开关可以有效的抑制串扰问题,在全光网络通信中具有一定的应用。
Micro optical element plays an important role in modem optics. By making the micro blazed-grating array of eight levels and controlling the parameters of period of blazed-grating, it could fulfill the functions of 2×2, 4×4 and 8×8 optical switch. The characteristic of micro blazed-grating optical switch is transparence and non-conversion of the signal of optical-electrical or electrical-optical. To analyze the crosstalk of output signal of micro blazed-grating, it is proved that micro blazed-grating could restrain crosstalk, and apply it in the field of all optical interconnection.
