High-Q nanocavities in semiconductor-based three-dimensional photonic crystals
S. Takahashi, T. Tajiri, K. Watanabe +3
We experimentally demonstrated high quality factors (Q-factors) of nanocavities in three-dimensional photonic crystals by increasing the in-plane area of the structure. Entire stru…
Topological photonic crystal nanocavity laser
Yasutomo Ota, Ryota Katsumi, Katsuyuki Watanabe +2
Topological edge states exist at the interfaces between two topologically-distinct materials. The presence and number of such modes are deterministically predicted from the bulk-ba…
Transfer-printed quantum-dot nanolasers on a silicon photonic circuit
A. Osada, Y. Ota, R. Katsumi +3
Quantum-dot (QD) nanolasers integrated on a silicon photonic circuit are demonstrated for the first time. QD nanolasers based on one-dimensional photonic crystal nanocavities conta…
