In future high speed optical communication networks all-optical signal processing will play an important role. The high transmission capacity of the fibre can be utilized by wavelength division multiplexing of time division multiplexed signals in the order of 10-20 Gbit/s per channel (wavelength). Therefore, signal transmission in a complex fibre network with many switching nodes requires the development of wavelength converters. A wavelength converter consisting of a semiconductor laser amplifier and an injection locked laser is investigated. The converter is insensitive to input polarization and wavelength. Input amplitude fluctuations are strongly reduced. The output signal is not inverted and nearly chirp-free.
