Latest Patents

One of his latest patents is titled "Radiation emitter." This invention describes a method of fabricating at least one radiation emitter by creating a layer stack that includes a first reflector, an active region, an oxidizable layer, and a second reflector. The process involves locally removing the layer stack to form at least one mesa, which consists of the first reflector, the active region, the oxidizable layer, and the second reflector. The method also includes vertically etching at least three blind holes inside the layer stack, exposing the oxidizable layer, and oxidizing it via the sidewalls of the blind holes. The oxidation front radially moves outwards from each hole, and the etching is terminated before the entire oxidizable layer is oxidized, resulting in at least one unoxidized aperture limited by at least three oxidation fronts.

Another significant patent is for a "Semiconductor laser and fabrication method thereof." This invention discloses a semiconductor laser that features a trim loss region in the inner ridge region of the surface of the transmission layer facing away from the substrate. A blind hole is provided in the trim loss region, and the distance from the bottom surface of the blind hole to the surface of the second cladding layer facing the substrate is smaller than the evanescent wavelength in the transmission layer. This blind hole can influence the optical field characteristics of light transmission in the semiconductor laser by affecting the evanescent wave.
