Abstract
Various embodiments of the present disclosure are directed towards a modulator device including a first waveguide and a heater structure. An input terminal is configured to receive impingent light. The first waveguide has a first output region and a first input region coupled to the input terminal. A second waveguide is optically coupled to the first waveguide. The second waveguide has a second output region and a second input region coupled to the input terminal. An output terminal is configured to provide outgoing light that is modulated based on the impingent light. The output terminal is coupled to the first output region and the second output region. The heater structure overlies the first waveguide. A bottom surface of the heater structure is aligned with a bottom surface of the first waveguide. The first waveguide is spaced laterally between sidewalls of the heater structure.
