Ultralow-loss silicon ring resonators

Biberman, Aleksandr; Shaw, Michael J.; Timurdogan, Erman; Wright, Jeremy B.; Watts, Michael R.

We experimentally demonstrate silicon ring resonators with internal quality factors of Q0 = 2.2 × 107, 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. © 2012 Optical Society of America.
