摘要

在基于平面波导或阵列波导光栅(AWG)的通道功率监测电路上，我们开发了一种简单的光信噪比监测方案。仿真和实验表明，与传统的可调滤波器方案相比，该方案具有更好的OSNR监测范围。AWG与周期陷波滤波器的结合使其更不受相邻信道的影响，进一步提高了OSNR的监测精度。

Adding OSNR monitoring functionality on AWG based power monitoring circuits

We have developed a simple scheme to implement optical signal to noise ratio (OSNR) monitoring on planar waveguide or arrayed waveguide grating (AWG) based channel power monitoring circuits. Simulation and experiment have demonstrated that our proposal will yield better OSNR monitoring range comparing with traditional tunable filter solutions. The combination of AWG and periodic notch filter makes it more immune to neighbor channel influence, and further improves the OSNR monitoring accuracy.
