Abstract (en)

[origin: WO0195443A1] A surface emitting laser with spatially varying optical loss to provide single mode operation. The optical loss may be introduced with an anti-phased ohmic contacts (4, 5). Current injection may be constricted to a diameter that is different than the diameter of the ohmic aperture (32), allowing for optimization of carrier profiles for high-speed performance. Methods for index guiding are introduced to further the reproducibility of the invention.
