Title: Douglas C Reid: Innovator in Optical Fibre Technology
Introduction
Douglas C Reid is a notable inventor based in Warwickshire, GB. He has made significant contributions to the field of optical fibre technology, holding a total of 4 patents. His work focuses on enhancing signal processing and amplification through innovative designs.
Latest Patents
One of Reid's latest patents is an amplifier/filter combination. This invention includes a fibre amplifier and a fibre reflection/transmission filter coupled to the amplifier. The fibre amplifier amplifies an input signal in response to pump light received from a laser. The fibre filter is preferably a chirped Bragg fibre filter, which filters out the unabsorbed portion of the pump light from the output amplified signal. It reflects the unabsorbed portion of the pump light back to the amplifier for re-absorption. The amplified signal is then transmitted by the filter to a receiver.
Another significant patent is the optical fibre lattice signal processor. This device comprises at least two coupling devices through which two optical fibres pass, allowing for optical coupling between them. The optical coupling devices are arranged in parallel, with each fibre experiencing a 180-degree turn between the couplers. The design accommodates both recursive and non-recursive arrangements, along with equal and arbitrary delays.
