Abstract
A design of a highly efficient second-harmonic generation hybrid
silicon carbide (SiC)-thin-film optical device is presented with a
normalized nonlinear conversion efficiency as high as
. It is shown that low-loss bends and
tapers in the SiC rib can be used to fold the device into any
desirable aspect ratio to meet design requirements or fabrication
limitations. Direct numerical integration of the coupled-wave
equations is used to simulate the generated second-harmonic output
power under a variety of fabrication tolerance considerations.
