Title: Innovations of David C W Herbert
Introduction
David C W Herbert is a notable inventor based in Worcs, GB. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Herbert's latest inventions is the Horizontal Access Semiconductor Photo Detector. This device comprises a horizontal light absorbing layer designed to convert light into photo-current. The configuration allows for the confinement of light within the layer in whispering gallery modes of propagation. The detector features a first waveguide portion and a second light confining portion, which work together to couple light into the detector and excite whispering gallery modes, significantly increasing the effective absorption coefficient of the light absorbing layer.
Another notable patent is the Avalanche Photo-Diodes arrangement. This invention provides a detector arrangement comprising two avalanche photo-diodes, which are reverse biased to just below their breakdown voltage. These diodes are arranged back-to-back and in series with an oscillating voltage source, allowing them to exceed their breakdown voltage out of phase with each other. This innovative design achieves low noise and can effectively distinguish dark counts.
