Title: Peh Wei Tan: Innovator in Optical Technologies
Introduction
Peh Wei Tan is a notable inventor based in Singapore, recognized for his contributions to optical technologies. With a total of two patents to his name, he has made significant advancements in the field of optical networks and semiconductor lasers.
Latest Patents
One of Peh Wei Tan's latest patents is the Optical Space Switch. This device is designed for optical space switching in optical networks. It features a broad area optical waveguide section with multiple electrodes extending along its length. When an electrical signal is applied to an electrode, it induces a local change in the effective refractive index of the waveguide, allowing light to preferentially propagate along a predetermined path based on the electrode configuration. This innovative device is implemented using indium phosphide (InP). Another significant patent is the Two-Section Distributed Bragg Reflector Laser. This semiconductor laser consists of a gain section and an adjacent Bragg section. The output laser light is emitted through a facet at the interface between air and the gain section. The Bragg section includes a distributed reflecting structure that ensures single longitudinal mode operation with a side-mode suppression ratio (SMSR) of 35 dB or more, effectively suppressing optical feedback.
