摘要： An optical modulator includes a ring resonator with a waveguide adjacent to and optically coupled to the micro-ring resonator. A p-i-n junction is formed about the ring resonator. An optional additional doped region may be formed opposite the waveguide from the ring resonator and when combined with the p-i-n junction forms a nearly closed p-i-n junction about the ring resonator. The ring resonator may be a silicon micro-ring resonator. Multiple different resonant frequency resonators may be coupled to the waveguide along with different detectors to multiplex light on the waveguide. The spectrum of the resonator may be controlled by an applied voltage. A prepulsing device may be used to enhance electrical transitions to enhance the speed of the modulator.

摘要： A high-index-contrast waveguide structure material used to guide light through a low-refractive-index material. In one embodiment, the waveguide structures are capable of guiding and confining light in such a way that very high optical intensity is obtained in a small cross-sectional area or gap filled with any material with sufficiently low refractive index, relative to the remainder of the structure.

摘要： A hybrid guided-mode resonance (GMR) grating, an optical filter and a method of optical filtering employ distributed Bragg reflection. The hybrid GMR grating includes a waveguide layer that supports a GMR having a GMR resonant frequency. The hybrid GMR grating further includes a diffraction grating that couples a portion of a signal incident on the hybrid GMR grating into the waveguide layer; and a distributed Bragg reflector (DBR) that reflects another portion of the incident signal. The coupled portion of the incident signal has a frequency corresponding to the GMR resonant frequency. The reflected portion has a frequency away from the GMR resonant frequency. The optical filter includes the hybrid GMR grating and a coupler. The method includes coupling an optical signal into the hybrid GMR grating and further coupling a reflected signal out of the hybrid GMR grating.
