Abstract

In this paper we present the rationale behind photonic integration of optical buffers for packet switching using optical delay lines. Our work on integrated buffers consisting of Indium-Phosphide-based gate matrix switches and silica-based delay lines is reviewed. Successful implementation of this hybridly integrated chip in a synchronously loaded optical packet buffer is shown. Integration of an optical buffer on the hybrid silicon platform, where active switches can be combined with a low-loss silicon delay line, is discussed and the results for a fully integrated 1.1-ns delay buffer are presented. We report on our current efforts to reduce the silicon waveguide loss to scale the hybrid silicon buffer to be able to store 40-byte packets.
