Research Abstract |
In this project, we have studied novel optical phenomena arising from the spatial interplay between the internal light field and wavefunctions of elementary excitations that is peculiar to nano-to-bulk crossover regime. As a result, we have experimentally clarified an ultrafast radiative decay with around 10 fs that is due to the large-scale interaction volume. Further, we have theoretically proposed an entangled photon-pair generation with both the high efficiency and ultra-low-noise by using such ultrafast modes.
