Paper Abstract

Lossless guided-wave switches with more than 30 dB of crosstalk-isolation are proposed and analyzed. The switches are comprised of branched channel waveguides with laser-like cross-sections. Optical gain, sufficient to overcome power-splitting losses, is provided by carrier-injection currents. Due to its low-noise properties, the single-quantum-well structure is found to be optimum for cascading switches into a multi-stage network. A lossless 1 x N network with 1024 switched outputs should be feasible.
