Abstract
One facet of each of a set of N semiconductor laser chips is provided with an antireflection coating through which the chip emission is coupled, via a wavelength multiplexer, with a partially reflecting Bragg reflector providing an N-way wavelength multiplexed laser output for pumping an optical amplifier. The wavelength multiplexer may be constituted by a cascade arrangement of Mach-Zehnders.
