Patent ID: 11953720
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A semiconductor device, comprising:
a substrate;
a first waveguide disposed on the substrate; and
an optical modulator disposed on the substrate and spaced apart from the first waveguide with a first distance, the optical modulator including:
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, wherein the optical coupling portion includes an intrinsic semiconductor,
wherein 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.
