Title
Two-Stage Taper Enhanced Ultra-High 
As 
S  of 0.0579 nm and side-coupled to a low-index Ti-diffused:LiNbO<sub>3</sub> straight waveguide was designed and fabricated. Using improved design and fabrication processes, a low 1.2-dB/cm propagation loss in the ring with over 30 dB of extinction ratio was demonstrated on a fabricated 1.7-cm-long path ring resonator with a 400- μm radius, which corresponds to a calculated intrinsic quality factor-Q as high as 3.5 × 10<sup>5</sup>. To our knowledge, this is the highest Q factor reported for chalcogenide ring resonator planar waveguide devices.</div></div>
