Abstract

A test bed employing a Ti:LiNbO, 4x4 nonblocking interconnection network has been implemented. As test bed data sourced, four video cameras each generate a 90 Mbs bit-stream. Input data streams feed into the 4x4 switch where any input channel can be switched to any output channel. The output signals are converted back into analog form and drive four video monitors. The Ti:LiNb0₃ switch is composed of 16 single-polarization directional couplers that are arranged in a crossbar configuration. The end-to-end insertion losses, including fiber pigtails, range from 6-25 dB, and the channel-to-channel switching efficiency varies from -6 dB to -16 dB. The paper will focus on the development of the test bed and the associated problems, which include: variation in electrode drive voltages, polarization effects, and coupler drift.
