Abstract :
We investigate the use of a multi-quantum well optical amplifier with tilted tapered waveguides and window structure for wavelength conversion in the 1.55 /spl mu/m range at up to 5 Gbit/s. A clear polarization independent regeneration is observed for wavelength down conversion over more than 30 nm and over a wide dynamic range of input extinction ratio.
