  • Patent number: 10338319
    Abstract: A modified directional coupler structure is used to provide a controllable time delay or phase shift for radiation propagating through the structure. A longitudinal displacement of the interaction region of the directional coupler relative to one or both of the waveguides of the directional coupler provides this effect. Double flexure arrangements can be used to provide longitudinal displacement with substantially no corresponding lateral displacement (or vice versa). In some embodiments, lateral and longitudinal displacement of the waveguides of the directional coupler are independently adjustable to provide full control of the power splitting and phase shift/time delay of the directional coupler.

  • Publication number: 20190065941
    Abstract: The disclosed embodiments relate to a system that implements a photonic neuron. This photonic neuron includes: an excitatory-input photo detector that converts an optical excitatory input signal into a corresponding electrical excitatory input signal; and an inhibitory-input photo detector that converts an optical inhibitory input signal into a corresponding electrical inhibitory input signal. It also includes an electrical neuron that receives the electrical excitatory and inhibitory input signals, and generates an electrical output signal, which includes periodic voltage spikes that are triggered by integration of the electrical excitatory and inhibitory input signals. Finally, the photonic neuron includes a light-emitting output device, which converts the electrical output signal into a corresponding optical output signal.

  • Patent number: 9368579
    Abstract: A robust fabrication process for selective area growth of semiconductors in growth windows is provided. Sidewall growth is eliminated by the presence of a spacer layer which covers the sidewalls. Undesirable exposure of the top corners of the growth windows is prevented by undercutting the growth window prior to deposition of the dielectric spacer layer. The effectiveness of this process has been demonstrated by selective-area growth of Ge and Ge/SiGe quantum wells on a silicon substrate. Integration of active optoelectronic devices with waveguide layers via end-coupling through the dielectric spacer layer can be reliably accomplished in this manner.

  • Patent number: 8924363
    Abstract: A method for correcting service manual textual inconsistencies. Extracting textual procedures from service documents stored in a memory of a service document storage device. Each term of an extracted textual procedure terminology is compared to a correlating target name terminology for identifying any matching terms by a processor. An overlap similarity is computed as a function of the identified matching terms from the extracted textual procedure terminology and the correlating target name terminology. A determination is made whether the overlap similarity is greater than a predetermined similarity threshold. The service documents are modified to change the extracted textual procedure terminology to the correlating target name terminology in response to the overlap similarity being greater than the predetermined similarity threshold and the extracted textual procedure terminology not exactly matching the correlating target name terminology.
