摘要：

We propose and demonstrate integrated signal-monitoring and connection-verification schemes for microelectromechanical-system (MEMS) optical crossconnects, The schemes utilize monolithically integrated beamsplitters and hybrid-integrated photodetectors as output signal-monitoring modules, To achieve connection verification, on-chip micromirror dithering is employed to encode optical signals with pilot tones that are used only internally to the crossconnect, The approaches described offer a potentially compact means of implementing several critical network-management and surveillance features.
