Title: Innovations by Dennis K Lam
Introduction
Dennis K Lam is a notable inventor based in Ottawa, Canada. He has made significant contributions to the field of optoelectronics, holding 2 patents that showcase his innovative spirit and technical expertise. His work focuses on enhancing the performance and efficiency of photoconductors and optoelectronic assemblies.
Latest Patents
One of his latest patents is for a "Depleted Channel Photoconductor." This invention describes photoconductors with channels that lie in the surface depleted region of a GaAs structure. These devices operate with nanoampere bias current and exhibit photoconductive gain. Unlike other photoconductors, they maintain low frequency responsivity comparable to that in the GHz region, which alleviates the need for equalization in receiver applications. Additionally, these devices demonstrate over 60 dB isolation as optoelectronic switches.
Another significant patent is for an "Optoelectronic Assembly and Method of Making the Same." This assembly converts signals between optical and electrical forms. It consists of a dielectric substrate and a semiconductor substrate, which are fabricated separately and then brought together. The dielectric substrate features a pair of metallic electrodes and a waveguide, while the semiconductor substrate contains an active optoelectronic device. This invention is particularly advantageous for forming large-scale integrated optoelectronic circuits and switching networks.
