Research Abstract

Increasing demand for info-corn technology requires development of new frequency region of electromagnetic wave. Paricularly. the frequency range of THz has not been well devloped for practical applications.
In this research, we intended to develop semiconductor integrated devices for generating coherent THz electromagnetic field as a fundamental technologies for constructing T-bit information network systems in the 2L^<st> century. We aim at contributing to practical application of THz and femtosecond technologies.
First, we developed a new THz detection devices by using low temperatiure GaAs growth and integration of photoconductive dipole antenna for irradiation and detection of THz electromagnetic field. As a result. sensitivity is improved by a factor of 25 compared to conventional type of detector. Next, we designed and developed microcavity quantum well structures for new type of coherent THz electromagnetic wave generator. This utilizes cavity polariton effect in semiconductors which was discovered by ourselves in 1992. By measuring reflectivity response of the device which was photo-pumped, we succeed in observing THz modulated optical signal form the device. This results partly establish fundamentals of a new type THz electromagnetic wave generator, which is important for information and communication technologies in the 21st century including microwave photonics.
