Laser assembly for pumping optical amplifiers |
| abstract |
One facet (10b) of each of a set of N semiconductor laser chips (10) is provided with an antireflection coating (10a) through which the chip emission is coupled, via a wavelength multiplexer (12), with a partially reflecting Bragg reflector (14) providing an N-way wavelength multiplexed laser output for pumping an optical amplifier (16). The wavelength multiplexer may be constituted by a cascade arrangement of Mach-Zehnders (12, 40 and 41). |
