Abstract
A photonics integrated circuit includes a first waveguide and a second waveguide. A portion of the first waveguide has a first cladding with a first refractive index. The second waveguide includes a second cladding with a second refractive index different from the first refractive index. Also disclosed is a test circuit for a photonics integrated circuit. The test circuit can be used to determine waveguide losses, and used to tune the waveguide losses.
