Outline of Final Research Achievements |
Since "Terahertz Wave" of which frequency between 0.1 to 10THz have been known as attractive electromagnetic wave spectra for innovative applications, there is a strong demand of solid state sources to generate intense terahertz waves. Terahertz emission phenomena from intrinsic Josephson junctions made of Bi-2212 high Tc superconductor arouse our interests from application viewpoint. This research has been devoted to understand the mechanism of terahertz emission based on a combination of the ac Josephson effect and plasma resonances in junction to increase terahertz output power. We also develop an industrially applicable device structure made of monolithic Bi-221 thin film having an advantage in heat dissipation. The monolithic IJJ exhibits excellent heat dissipation and the maximum emission is observed at 75K near below 77K. The maximum emission power is estimated to be more than 5μW. It is also examined to generate terahertz emission due to non-linear optical response.
