High speed and low loss GeSi/Si electro-absorption light modulator and method of fabrication using selective growth
An optoelectronic device includes an input waveguide structure that receives an input optical signal. A GeSi/Si waveguide structure receives from the input waveguide the input optical signal and performs selective optoelectronic operations on the input optical signal. The GeSi/Si waveguide structure outputs an optical or electrical output signal associated with the selective optoelectronic operations performed on the input optical signal. An output waveguide structure receives the output optical signal from the GeSi/Si waveguide structure and provides the optical output signal for further processing.
