摘要: All-optical switches are fundamental building blocks for future, high-speed optical networks that utilize time division multiplexing (OTDM) techniques to achieve single channel data rates exceeding 100 Gb/s. Interferometric using semiconductor amplifier (SOA) non-linearities perform efficient switching with < 500 fJ of control energy and approaching sampling bandwidths nearly 1 THz. In this paper, we review work underway at Princeton University characterize demonstrate these as processing elements in practical systems. Three interferometric switch geometries presented characterized. We discuss limitations on the minimum temporal width window prospects integrating devices. Using demultiplexers, two 100-Gb/s testbeds photonic packet switching. addition networking applications, have explored simultaneous wavelength conversion pulse management. also designed high bandwidth systems SOA-based analog gates capable analyzing waveforms GHz. believe devices represent a versatile approach all-optical variety applications can be performed without significantly changing device architecture.
