Title: Innovations of Timothy D Osentowski
Introduction
Timothy D Osentowski is a notable inventor based in San Jose, CA (US). He has made significant contributions to the field of opto-electronic devices, holding a total of 4 patents. His work focuses on enhancing the efficiency and functionality of light-emitting diodes and high band-gap devices.
Latest Patents
One of his latest patents is for a light-emitting diode with a thick transparent layer. This innovative LED design includes a light generation region situated on a light-absorbing substrate, which is complemented by a thick transparent layer. This layer ensures that an increased amount of light is emitted from the sides of the LED while minimizing light absorption by the substrate. The thickness of this transparent layer is determined based on its width and the critical angle for internal light reflection. Additionally, the thick transparent layer can be positioned above, below, or both above and below the light generation region, and may be made from different materials than the light generation region.
Another significant patent by Osentowski is a method of making a high band-gap opto-electronic device. This device is formed by epitaxially growing the device section in a lattice-matched (Al.sub.x Ga.sub.1-x).sub.y In.sub.1-y P-GaAs system. The band-gap of the epitaxial layer increases with the variable x. Instead of directly growing the device section on the GaAs substrate, a transitional layer of (Al.sub.x Ga.sub.1-x).sub.y In.sub.1-y P is grown, graded in x and temperature while maintaining y=0.5. This invention includes various device structures such as homojunctions, heterojunctions, and separate confinement quantum well heterostructures.
