Abstract
In one example embodiment, an optical circuit for optical modulation of light may include an input waveguide including a first thickness, an optical modulator including a second thickness, and a tapered transition that optically couples the optical modulator and the input waveguide. The second thickness may be smaller than the first thickness. The tapered transition may adiabatically transform the optical mode of the input waveguide to the optical modulator.
