Title: Innovations of Andrew G Dentai

Introduction

Andrew G Dentai is a notable inventor based in Highlands, NJ (US). He has made significant contributions to the field of photonics, holding two patents that showcase his innovative spirit and technical expertise. His work primarily focuses on advanced optical devices that enhance data transmission and processing.

Latest Patents

One of Dentai's latest patents is for a demultiplexing photodetector. This invention features a three-terminal, totally integrated demultiplexing photodiode that can develop information present simultaneously at two wavelengths into two separate currents. The design incorporates two quaternary layers of indium, gallium, arsenide phosphide with unequal bandgaps, separated by a buffer layer of n-type indium phosphide. This configuration allows for operation at longer wavelengths, enabling the detection of shorter wavelengths in the radiation.

Another significant patent is for a unidirectional optical device and regenerator. This light-activated light-emitting device includes at least one p-n junction with electrodes that confine light emission to a specific area. The device can be activated by light impinging on the junction outside the confined area, utilizing two optical fibers—one for input and the other for output. This innovation is particularly advantageous for use in optical fiber data busses or optical logic arrays, as it prevents light feedback between adjacent devices, thereby avoiding spurious switching.
