Abstract:Continuous terahertz waves have important applications in scientific and industrial fields such as medicine and information technology. Many methods (the quantum cascade laser and the photomixing method, etc.) are developed as a continuous terahertz wave source. However, there is a fault that intensity of continuous terahertz waves by present source is very low in range of 1-4THz. Therefore, new source of the continuous terahertz waves is necessary. New hopeful method of a generating terahertz waves via excitation of intrinsic Josephson plasma (IJP) in high-temperature-superconductor device was proposed in 1994. R & D of this device is very difficult because of nonlinearity of IJP that occurs in a very broad time (10as to ns) and space(1nm to several hundred _m). Furthermore, this device requires a nano-scale electrode, wave-guide, wiring etc. Therefore, we need a large-scale simulation to develop the device. We have performed a large-scale simulation and found a optimum condition of generation of continuous terahertz waves, using Earth Simulator. We present a result of large-scale simulation for the optimum condition of generating continuous terahertz waves through the nano-scale high-temperature-superconductor device and future challenges of development of this nano-scale device.
