Latest Patents

One of his latest patents is for a vertical cavity surface emitting device with a buried index guiding current confinement layer. This invention involves a vertical cavity surface emitter device, such as a VCSEL or RC-LED, which contains a buried index-guiding current confinement aperture layer. This layer is grown and lithographically processed to define the position, shape, and dimension of an inner aperture. The aperture allows for both current and optical confinement, leading to higher optical power output and improved thermal conductivity.

Another significant patent by Kapraun focuses on epitaxial growth on a gallium arsenide phosphide capped material on a gallium arsenide substrate. This semiconductor device fabrication method includes a growing process followed by a capping process, where a phosphor-containing material cap layer is deposited over a final GaAs-based layer. This innovative method allows for continued processing without creating an oxide layer on the final GaAs-based layer, enhancing the efficiency of semiconductor device fabrication.
