Abstract
The present disclosure provides semiconductor devices and photonic circuits. The semiconductor device includes a substrate and an optical modulator disposed on the substrate. The optical modulator includes a first electrical coupling portion having a first type doping, a second electrical coupling portion having a second type doping, and an optical coupling portion disposed between the first electrical coupling portion and the second electrical coupling portion, where the optical coupling portion includes an intrinsic semiconductor. The optical modulator is configured to receive a first voltage through the first electrical coupling portion and the second electrical coupling portion to decrease a resonant wavelength of the optical modulator.
