Ming Zhou is a notable inventor based in San Jose, CA, who has made significant contributions to the field of optical devices. With a total of 5 patents to his name, he has focused on developing advanced technologies that enhance the functionality and efficiency of miniature optical devices.

Latest Patents

One of Ming Zhou's latest patents is for miniature circulator devices and methods for making the same. These miniature optical devices, including circulator array devices, are fabricated using thin film coating technology. A typical optical device includes two refraction elements arranged opposite each other along a propagation axis and coupled on opposite ends to first and second polarization orientation elements. The first and second polarization beam splitter (PBS) elements are coupled to the respective polarization orientation elements. The refraction elements consist of complementary Wollaston Prism elements or Rochon Prism elements. Each polarization orientation element includes a Faraday rotator element, and in some embodiments, a half-wave plate formed using thin film coating techniques. The Faraday rotator elements are periodically poled in some embodiments using selective poling techniques to create oppositely oriented magnetic domains. This innovation allows for polarization rotations of 45 degrees in both clockwise and counter-clockwise directions to be simultaneously achieved on the same magnetic garnet. Periodically etched half-wave plates are also utilized in some embodiments.
