High-index contrast Ge-doped silica waveguide technology: optical performance and application to ultralow-loss ring resonators
TL;DR: In this article, a 3.5% index contrast Ge-doped silica planar technology with a propagation loss /spl les/0.10 dB/cm was used to fabricate ring resonators with a round-trip loss of 0.03 dB.
