Outline of Final Research Achievements

We have investigated the enhancement of terahertz electromagnetic waves due to exciton quantum beat generated by difference frequency mixing excited by two continuous wave lasers in a semiconductor multiple quantum well. The maximum intensity was obtained by two continuous wave lasers with the energies of heavy-hole and light-hole excitons at room temperature. Generally, in the zincblende structure semiconductors, the oscillator strength of heavy-hole excitons is three times larger than that of light-hole excitons, so that the maximum intensity was expected at the heavy-hole exciton energy. However, in the experiment, the maximum intensity was obtained at the light-hole exciton energy, which suggests that it is possible to enhance the difference frequency mixing process by quantum beat.
