摘　　要：基于衍射型OPM(Optical Power Monitor)能够在设定的波长范围内对不同波长的光信号进行实时采样,其稳定性好并能快速测量。采用阵列波导光栅对波分复用信号进行分解复用,不同波长的光信号分别经过相应的分束器,探测器阵列对各路通道的光进行探测。探测器阵列能够探测出各波长的光功率、光电流以及插入损耗,计算出耦合后的响应度。分析响应度和插入损耗与波长的关系,得出此结构系统能够应用在光差分复用器中。OPM（Opticala Power Monitor）based on diffraction could have real-time sampling on different wavelengths in the setting wavelength range.It has a good stability and a fast measurement.Demultiplexing WDM signals with AWG,optical signals of different wavelengths go through the appropriate beam splitter,respectively.And then,PD（Photodiode）arrays detect light signals from various channels.Optical power,optical electricity and insert loss of each wavelength can be detected by PD arrays,moreover,responsivity can also be calculated.The OPM system can be used in the OADM module after the analysis of insert loss and responsivity with wavelength.
