Title: Innovations by Brian Chiang in Optical Technology
Introduction
Brian Chiang is an accomplished inventor based in Albany, CA. He has made significant contributions to the field of optical technology, holding 2 patents that showcase his innovative approach to integrated optical components.
Latest Patents
Chiang's latest patents include advancements in integrated optical components with variable attenuation or switching, and tap detector functions. His first patent focuses on an integrated optical component that combines the functions of a Variable Optical Attenuator (VOA), a tap coupler, and a photo-detector. This innovation reduces the size, cost, and complexity of these functions. Additionally, the component utilizes a rotatable mirror to adjust light coupling from input ports to output ports. A pinhole with a reflective surface at the core end face of the output fibers allows a portion of the output optical signal to be reflected to a photodiode chip, providing an indication of the optical power being coupled.
The second patent addresses a highly temperature stable filter for fiber optic applications. This invention alters the optical thickness of devices such as interference filters or optical isolators by applying stress, which changes their frequency or isolation characteristics. By clamping the device to a member with a different temperature expansion coefficient, tension or compression is applied in response to temperature changes, partially canceling shifts in optical characteristics.
