Title:
CW−OSCILLATION MILLIMETER WAVE&sol SUBMILLIMETER WAVE LASER COMPOSED OF INTEGRATED CIRCUIT INCLUDING INTRINSIC JOSEPHSON DEVICE
Document Type and Number:
WIPO Patent Application WO/2003/019738
Kind Code:
A1
Abstract:
A cw−oscillation millimeter wave&sol submillimeter wave laser composed of an integrated circuit including a cw−oscillation intrinsic Josephson device and fabricated by integrating a terachrtz−band antenna and a choke circuit by using a BSCCO single−crystal device. The laser comprises a DC current source (IA) and a two−dimensional array where a very large number of (more than 10,000) of intrinsic Josephson junction devices (41) connected to the DC current source (IA) including a terahertz−band antenna and a choke circuit are interconnected in series and parallel. By injecting a DC current from the DC current source (IA), a cw millimeter wave&sol submillimeter wave laser beam can be generated.
