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.
