Introduction

Yuanji Tang is a notable inventor based in Palo Alto, California. He has made significant contributions to the field of optical switching technology, particularly through his innovative patent.

Latest Patents

Yuanji Tang holds a patent for an "Optical switching device using holographic polymer dispersed liquid crystals." This invention features a thin holographic optical switch utilized in liquid crystal display devices. The device comprises opposing transparent substrates, transparent electrodes situated between the substrates, and a diffraction grating positioned between the electrodes. The diffraction grating is composed of regions of transparent polymerized photopolymers and cholesteric liquid crystal micro-droplets. Notably, the refractive indexes of the photopolymers and liquid crystal are substantially the same when the electrodes maintain the same potential. The holographic optical switch transmits broadband LED light when the potential difference between the electrodes is zero and operates independently of polarization. Conversely, it diffracts broadband LED light when the potential difference is non-zero, also remaining polarization independent.
