Title: The Innovative Contributions of Karen A Grim-Bogdan
Introduction
Karen A Grim-Bogdan is a notable inventor based in Greenwich, PA (US). She has made significant contributions to the field of semiconductor lasers, holding 2 patents that showcase her expertise and innovative spirit. Her work has had a profound impact on the development of advanced laser technologies.
Latest Patents
Karen's latest patents include a "Method of improving laser yield for target wavelengths in epitaxial" and a "Method for making multiple wavelength semiconductor lasers on a single substrate." The first patent describes a method for producing a batch of MQW lasers from a plurality of wafers with varying doping concentrations. This process involves epitaxially growing an InGaAsP quaternary layer on the substrates in a metal-organic chemical vapor deposition (MOCVD) reactor. The method effectively segregates the substrates into groups based on doping concentrations, allowing for batch production of lasers at specific target wavelengths for each group.
The second patent outlines a technique for fabricating different wavelength semiconductor lasers on a single substrate by establishing a thermal gradient during epitaxial growth. This innovative approach results in a variation of composition that produces corresponding variations in laser wavelength across the substrate. The thermal gradient is achieved by applying a patterned layer of material on the substrate's backside, which is removed after the substrate is lapped to its final thickness.
