The PLZT-based monolithic tunable wavelength filter with multiple channel phase shifters was designed and fabricated. Crosstalks of the filter were -14 dB for TE polarized light and -13 dB for TM polarized light, respectively. The filter 3-dB bandwidth and the response time were 110 GHz and less than 40 ns for both polarizations. The operation method of the spectrum control circuit was studied. The variable bandwidth filtering and arbitrary delay operation were successfully demonstrated with the spectrum control circuit. The silica-based arrayed-waveguide gratings and the PLZT-based optical switches were hybrid integrated and it showed the fast wavelength selective operation with a switching time of less than 13 ns.

设计和制造了带有多个通道相变的基于PLZT的整体可调波长滤波器。对于TE极光的光，滤波器的串扰为-14 dB和-13 dB，用于TM极化光。两个极化的滤波器3-DB带宽和响应时间为110 GHz，小于40 ns。研究了频谱控制电路的操作方法。频谱控制电路成功证明了变量带宽滤波和任意延迟操作。基于二氧化硅的阵列波导光栅和基于PLZT的光学开关是混合的，它显示了快速波长的选择性操作，开关时间小于13 ns。
