Abstract:
1. A light source apparatus comprising: a plurality of light sources with an active layer, the light sources being adjacent to each other, each of the light sources having a cavity defined by a defect in a photonic crystal comprising a periodic structure; a plurality of first electrodes corresponding to each of the light sources, each of the first electrodes being electrically separated from each other by a gap to independently drive each of the light sources; a second electrode; a common waveguide without the active layer, the common waveguide being configured to optically couple to light emitted from each of the light sources by using each of the first electrodes and the second electrode, so that output optical power from the common waveguide is in a range between several tens of milliwatts and several watts; and an additional plurality of light sources adjacent to each other and positioned across from the common waveguide relative to the plurality of light sources.
