| Outline of Final Research Achievements |
The purpose of this study is to demonstrate photon pair generation by means of ultrasonic vibrating mirrors covered with metamaterials that can localize electromagnetic waves. One of surface of silicon mirror was covered with metamaterials constructed with metallic split rings and bars. Piezoelectric ZnO was coated on the other surface of the mirror as an ultrasonic vibrator.
By terahertz time-domain spectroscopy, the group velocity delay due to the electromagnetically induced transparency was confirmed. The reflection echo related to the ultrasonic vibration at 400 MHz was confirmed in the ultrasonic waveform. However, generation of the electromagnetic waves was not confirmed. The study is now in progress.
