摘要：

Optical buffering has been one of the major technical challenges in realizing optical packet switching routers and interconnects. We demonstrate a compact optical buffer module, comprising an InP 1 x 8 phased-array switch and a silica-based delay line circuit. The integrated delay line circuit is fabricated on the silica-based planar-lightwave circuit (PLC) platform, and has the ladder architecture for reducing the size. In addition, variable optical couplers are integrated to achieve effective power equalization. Tunable and uniform buffering of up to 21 ns is obtained with 3-ns temporal resolution.
