Varrazza, R and Yu, S and Owen, M and Khrushchev, I and Penty, RV and White, IH and Dewar, SV (2000) All-optical switching in a vertical coupler space switch employing photocarrier-induced nonlinearity. Pacific Rim Conference on Lasers and Electro-Optics, CLEO - Technical Digest. pp. 467-468.Full text not available from this repository.
A novel compact integrated nonlinear optical switch is demonstrated. Using a high-power picosecond pulse of 5-ps pulsewidth and 250-MHz repetition rate, all-optical switching with a contrast ratio of 23 dB has been achieved using an in-fiber input power < 14 dBm (100 pJ/pulse). The switch speed depends on the carrier sweep-out time, which can be reduced to the 10 ps range by either applying a reverse bias or by introduction of carrier recombination centers in the active layer.
