Semiconductor crystal for generating terahertz waves, terahertz wave-generator incorporating the crystal, semiconductor crystal for detecting terahertz waves, and terahertz waves detector incorporating the crystal

摘要

A terahertz wave-generating semiconductor crystal includes a zincblende-type III-V compound semiconductor crystal that generates terahertz wave pulses upon application of an ultrashort light pulse in the optical communication band serving as a pump beam.
