Title: The Innovations of Patrick Abraham
Introduction
Patrick Abraham is an accomplished inventor based in Santa Barbara, CA. He has made significant contributions to the field of electro-optic devices, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is titled "Ridge waveguide device surface passivation by epitaxial regrowth." This patent describes a method for reducing surface recombination in areas adjacent to a mesa in devices that contain both active and passive sections. The method involves growing a thin epitaxial layer of material with a larger bandgap than the waveguide material, which is achieved through metalorganic vapor phase epitaxy (MOVPE). This layer is designed to be non-intentionally doped to prevent surface leakage paths while being thin enough to allow carriers to diffuse and thermalize in the waveguide layer.
Another notable patent is the "Fused vertical coupler for switches, filters and other electro-optic devices." This invention details a vertical directional coupler that is fabricated using wafer fusion, allowing for a very short coupling length. This technology enables the creation of switches, filters, and other electro-optic devices by facilitating vertical coupling between arrays through fused regions.
