Abstract
The present disclosure provides a semiconductor device, a photonic circuit, and a method for adjusting a resonant wavelength of an optical modulator. The semiconductor device includes a substrate, a first waveguide disposed on the substrate, a second waveguide disposed on the substrate and spaced apart from the first waveguide by a first distance, and a heater disposed on the second waveguide and having a first terminal and a second terminal. In addition, the first terminal of the heater is configured to receive a first electrical signal; the second terminal of the heater is configured to receive a second electrical signal; and the heater is configured to carry a time-varying current in response to the first electrical signal and the second electrical signal.
