A semiconductor light source comprises superluminescent diodes (SLDs) disposed on a substrate having a facet, channels separating the SLDs, and a mode expander region. Each SLD has a diamond shaped active region such that the front and rear end of each SLD ends in a taper. The mode expander region is disposed on at least one side of the tapers of the SLDs and is tapered into a waveguide extending to said facet. |
