Abstract
A surface emitting semiconductor laser system having an outcoupling aperture on a central waveguide. At either end of the central waveguide are means for reflecting a plurality of different wavelengths of light such that multiple wavelengths are outcoupled through a single outcoupling aperture. Means are provided by which the different wavelengths can be independently modulated.
