Abstract :
A new type of semiconductor optical amplifier (SOA), consisting of a singlemode waveguide with a 1/spl times/1 multimode-interferometer (MMI) section, is proposed and experimental results presented. Maintaining single lobed outputs these new MMI amplifiers show improvements of 2 dB in gain and 5 dB in saturation output compared to regular single-stripe SOAs.
