Title: Tien-Hsin Chao: Innovator in Optical Communications and Holographic Memory
Introduction
Tien-Hsin Chao is a prominent inventor based in Valencia, California, known for his significant contributions to the fields of optical communications and holographic memory. With a remarkable portfolio of 16 patents, Chao has developed innovative technologies that enhance satellite communications and data storage capabilities.
Latest Patents
Among his latest patents is the "High bandwidth optical links for micro-satellite support." This invention encompasses a method, systems, apparatus, and device that enable high bandwidth satellite communications. An onboard tracking detector, installed in a low-earth orbit satellite, detects the position of an incoming optical beam received or transmitted from a ground station. The tracker electronics determine orientation information of the incoming optical beam based on its position. Control electronics receive this orientation information and manage the waveguide drive electronics, which control the voltage provided to an electro-optic waveguide beam steering device. This device steers an outgoing optical beam to one of the ground stations based on the voltage.
Another notable patent is the "High density, high bandwidth multilevel holographic memory." This invention provides a holographic memory system and apparatus that allows for the storage of multibit holograms in a photorefractive crystal. A single laser diode emits a collimated laser beam to write and read pages of multibit data from the photorefractive crystal. A multilevel spatial light modulator encodes the data on an input beam split from the laser beam, while imaging relay lenses and mirrors facilitate the reading and writing processes.
