摘要： An optical modulator and related methods are described. In accordance with one embodiment, the optical modulator comprises a waveguide for guiding an optical signal, and further comprises a ring resonator disposed in evanescent communication with the waveguide for at least one predetermined wavelength of the optical signal. The optical modulator further comprises a semiconductor pnpn junction structure that is at least partially coextensive with at least a portion of a resonant light path of the ring resonator. The optical modulator is configured such that the semiconductor pnpn junction structure receives an electrical control signal thereacross. The electrical control signal controls a free carrier population in the resonant light path where coextensive with the pnpn junction structure. A resonance condition of the ring resonator at the predetermined wavelength is thereby controlled by the electrical control signal, and the optical signal is thereby modulated according to the electrical control signal.
