Latest Patents

Wei-Hung Loh holds a patent for an "Ultrahigh frequency optical self-modulator." This invention focuses on polarization self-modulation of a laser, which produces high-frequency optical modulation without the need for high-speed electronics. The technology involves inserting a polarization converter into a laser cavity, which periodically rotates the polarization of the laser light as it circulates. The modulation frequency is determined by the cavity length. In one configuration, a quarter-wave retardation plate serves as the intracavity polarization converter in a Fabry-Perot laser. In another embodiment, an electro-optic crystal acts as an electronically-controllable half-wave retardation plate. This patent showcases his innovative approach to optical technology.
