Title: Charles Garvin: Innovator in Optoelectronic Technologies
Introduction
Charles Garvin is a notable inventor based in Adelphi, MD (US). He has made significant contributions to the field of optoelectronics, holding 2 patents that showcase his innovative approach to technology. His work primarily focuses on neural architectures and advanced imaging techniques.
Latest Patents
Garvin's latest patents include an optoelectronic waveguide neural architecture. This invention describes a GaAs-based optical waveguide structure designed for neural networks. The architecture features at least three electrically active components that are isolated from one another. The waveguide parameters ensure that the laser light propagating through it is single-mode in both transverse and lateral directions. Additionally, a superlattice structure is incorporated in the waveguide core, resulting in electroabsorption of the input laser light. An electric field is applied to the active components to modulate the light transmission properties of the core material.
Another significant patent involves phase contrast image microscopy using optical phase conjugation. This method produces intensity contrast images from phase details in transparent phase objects while eliminating background artifacts and speckle. A coherent light source is directed through the transparent phase object and focused into a photorefractive hologram recording crystal, forming a temporary volume phase hologram. The process allows for the creation of a phase conjugate beam that enhances image clarity by subtracting coherent artifacts from the final intensity image.
