Efficient regenerative wavelength conversion at10 Gbit/s over C- and L-band(80 nm span) using a Mach-Zehnder interferometer with monolithicallyintegrated semiconductor optical amplifiers

A demonstration is presented of 10 Gbit/s 2R regenerative wavelength up- and down-conversion within the C-band as well as up-conversion to the L-band using a monolithically integrated Mach-Zehnder interferometer module with semiconductor optical amplifiers (MZI-SOAs). The converted output signals exhibit very low noise and chirp which is accompanied by a negative power penalty.
