Latest Patents

Yun-Shik Lee holds a patent for the "Generation of terahertz radiation in orientation-patterned semiconductors." This patent describes a method for generating THz radiation by illuminating a semiconductor crystal with an optical pulse train. The semiconductor crystal consists of alternating parallel crystal domains, each with an inverted crystal orientation compared to adjacent domains. The optical pulse train propagates perpendicularly to the domain boundaries, leading to the generation of THz radiation through optical down-conversion mediated by the semiconductor crystal. The efficiency of THz generation can be enhanced by placing the semiconductor crystal within an external resonant cavity, a laser cavity, or an OPO cavity. The semiconductor crystal may include materials such as zinc-blende, III-V, or II-VI semiconductors.
