Variable group delay in a metamaterial with field-gradient-induced transparency
Yasuhiro Tamayama, Toshihiro Nakanishi, Masao Kitano
We realize variable control of the group delay in an electromagnetically induced transparency-like metamaterial. Its unit cell is designed to have a bright mode and a dark mode. Th…
Electromagnetic response of a metamaterial with field-gradient-induced transparency
Yasuhiro Tamayama, Toshihiro Nakanishi, Yasuhiro Wakasa +3
We investigate a dynamically controllable electromagnetically induced transparency-like metamaterial. The unit structure of the metamaterial consists of a low-quality-factor resona…
Enhancement of second harmonic generation in a doubly resonant metamaterial
Tetsuo Kanazawa, Yasuhiro Tamayama, Toshihiro Nakanishi +1
We investigate second harmonic (SH) generation in a doubly resonant metamaterial. We show that SH generation can be enhanced when the resonant condition is satisfied for the SH fre…
Nonlinear behavior of geometric phases induced by photon pairs
H. Kobayashi, Y. Ikeda, S. Tamate +2
In this study, we observe the nonlinear behavior of the two-photon geometric phase for polarization states using time-correlated photons pairs. This phase manifests as a shift of t…
