Abstract

Low-loss channel waveguides in a ring-resonator configuration have been fabricated; measured results show a finesse of 16 and a coupling efficiency of 2%. Total losses, including coupling, material, bending, and fabrication losses, were 0.05 ± 0.01 dB/cm.

Plot of resonator coupling versus waveguide attenuation for various peak transmissions and finesses. Attenuation can be found from the measured quantities’ coupling and finesse, e.g., for a measured finesse of 16 and a coupling of 2%, attenuation is about 0.05 dB/cm.

Experimental setup for resonator finesse measurements. Resonator coupling was measured directly by prism coupling into the ring (P5/P6) and coupling out of ring (P6/P5) and channel (P2/P4).
