Enhanced 10-Gb/s operation of bandwidth-limited R-SOAs without electronic equalization

Abstract

By simply using a selected WDM demultiplexer, we obtain enhanced 10-Gb/s operation of a Reflective SOA having <;1 GHz bandwidth by using simple direct detection. The scheme is robust to wavelength drifts up to 10 GHz. Error free operation is experimentally achieved over 20 km fibre, with no need for electronic equalization or FEC.
