摘要： A filter apparatus is described that includes an electrical input signal, an optical source, an optical modulator, first and second pluralities of photonic delay lines, an optical switch, a combiner, and a photodetector. The optical modulator is coupled to the electrical input signal and the optical source. The first plurality of photonic delay lines are coupled to the optical modulator. The optical switch is coupled to the optical switch. The combiner combines the outputs of the second plurality of photonic delay lines to provide a combined output. The photodetector is coupled to the combined output of the combiner to provide a first filtered output of the electrical input signal.

摘要： A method and apparatus are described for allowing diagnostics of a Passive Optical Network without significant loss of service to active customer sites. A plurality of primary transmitters operating at a first wavelength band are coupled to an optical switch of an optical network operating at a first wavelength band. A backup transmitter operating at the first wavelength band is coupled to a first input of a wavelength division multiplexer. An optical device operating at a second wavelength band is coupled to a second input of the wavelength division multiplexer. An output of the wavelength division multiplexer is coupled to an input of the optical switch. Outputs of the optical switch are coupled to a plurality of optical splitters. Each splitter has a plurality of optical outputs. The optical switch is reconfigured such that one of the optical switch outputs that was carrying traffic from one of the primary transmitters carries traffic from the backup transmitter after reconfiguring the optical switch.

摘要： Embodiments of the invention describe (M)MPICs, which include RF processing components and heterogeneous silicon photonic components that include a first region of silicon material and a second region of non-silicon material with high electro-optic efficiency (e.g., III-V material). Said heterogeneous silicon components are fabricated from the silicon and non-silicon material, and therefore may be interconnected via silicon/non-silicon waveguides formed from the above described regions of silicon/non-silicon material. The effect of interconnecting these components via said optical waveguides is that an RF signal may be processed using photonic components consistent with the size of an MMIC, without the need for any optical fibers; therefore, embodiments of the invention describe a chip scale microwave IC that has the broad optical bandwidth of photonics without any optical interfaces to fiber. Furthermore, in some embodiments, the RF processing components, heterogeneous photonic components, and control circuitry may be included in the same chip-scale package.
