Abstract

Optical amplifier noise in optical millimetre-wave links is analysed. It is shown that signal-amplified spontaneous emission (ASE)beat noise may be reduced by 3 dB for two-tone optical spectra, in contrast to conventional intensity-modulated links where signal-ASE noise cannot be modified by optical filtering. A reduction in signal-ASE noise of 2.5 dB is experimentally demonstrated for an erbium-doped fibre amplifier using a 30 GHz optical millimetre-wave source and a Bragg fibre grating.
