Rapidly Tunable All-Optical Wavelength Converter Based on Single Semiconductor Optical Amplifier Delay Interferometer

We demonstrate a rapidly tunable 10 Gbit/s all-optical wavelength converter based on a semiconductor optical amplifier delay interferometer configuration and a tunable laser. The bit sequence on the incoming wavelength is converted alternatively to two different output wavelengths with 1.6 µs packet length. Power penalties are 1.1 dB for 60 ns spacing between wavelength packets.
