Ultralow-loss silicon ring resonators.
We experimentally demonstrate silicon ring resonators with internal quality factors of Q(0)=2.2×10(7), corresponding to record 2.7 dB/m propagation losses. Importantly, we show that these propagation losses are limited by bend loss, indicating that the propagation loss limit for silicon has not yet been reached.
