Outline of Final Research Achievements

Terahertz wave is expected to be used in such wireless communication systems due to its potentially broad bandwidth. In this presentation, we report on the detection of terahertz radiations from terahertz quantum cascade lasers (THz- QCLs) by up-conversion using the intense near-infrared with MgO:LiNbO3 crystal as a non-linear crystal. The near-infrared is generated from the microchip Nd:YAG laser based MOPA system. The up-converted signal was observed when the injection of the pulse current and the optical pulse pumping occurred at the same time. From this result, it is shown that the frequency up-conversion technique is useful to investigate the lasing dynamics of THz-QCLs.
And we investigate the EO polymer device which has a waveguide structure for up-conversion method.

Academic Significance and Societal Importance of the Research Achievements

テラヘルツ量子カスケードレーザーで発生させたテラヘルツ波と1μm帯の強力なパルス光の上方置換信号が発生できることを実験的に確認した。シクロオレフィンポリマーをクラッド材とした導波路構造について、これらのポリマーを高精度かつ密着性良く接合する技術開発を行い、800nm付近に高い性能を持つ導波路構造を持つポリマーを開発した。
このことによってテラヘラヘルツ波の発生および検出に新技術を提供し、大容量無線通信に向けた要素技術を開発した。
