Abstract
A silicon photonics platform with a reduced silicon layer thickness, which is suitable for hybrid thin-film lithium niobate traveling-wave electro-optic modulators, is used to design low loss waveguides, precise directional couplers, high-quality-factor silicon microring resonators and broad-top coupled microring filters. These designs are verified with experimental measurements and show a way to include such components without requiring a second layer of crystalline silicon of different thickness for this purpose.
