Dr. Ho's current resesarch program comprises three thrusts for the development of quantum electronic devices. A semiconductor becomes conducting when illuminated with ligh of the appropriate wavelength. Following a feasibility study, Dr. Ho's group has carried out an experimental demonstration of this idea at 2-4 GHz using a camera flashlight and a 10cm diameter silicon wafer. The second project focuses on laser ranging and the challenge of realizing an accurate, inexpensive, and simple device for measuring distances. An accuracy of 10 ppm has been achieved up to 20 meters distance.
Work is underway for further improvements.
The third experiment focuses on the design and fabrication of a spatial light modulator, which accepts spatial information at the infrared and reads out in the visible. To see a more detailed description of his work and recent publications, Click Here .
