Abstract: Universal linear components are provided. In general, a P input and Q output wave combiner is connected to a Q input and R output wave mode synthesizer via Q amplitude and/or phase modulators. The wave combiner and wave mode synthesizer are both linear, reciprocal and lossless. The wave combiner and wave mode synthesizer can be implemented using waveguide technology. This device can provide any desired linear transformation of spatial modes between its inputs and its outputs. This capability can be generalized to any linear transformation by using representation converters to convert other quantities to spatial mode patterns. The wave combiner and wave mode synthesizer are also useful separately, and can enable applications including self-adjusting mode coupling, optimal multi-mode communication, and add-drop capability in a multi-mode system. Control of the wave combiner and wave mode synthesizer can be implemented with single-variable optimizations.

Abstract: A hoop lock including a shackle and a crossbar, with the shackle having a pair of legs extending from a body portion, and each of the legs having a foot including a tip with a non-circular cross-section. The cross-bar includes a housing having a pair of foot-receiving openings and a pair of tip-receiving openings substantially aligned with foot-receiving openings. The tip-receiving openings are configured to matingly engage the tips such that the tips are rotationally coupled to the housing.

Abstract: Universal linear components are provided. In general, a P input and Q output wave combiner is connected to a Q input and R output wave mode synthesizer via Q amplitude and/or phase modulators. The wave combiner and wave mode synthesizer are both linear, reciprocal and lossless. The wave combiner and wave mode synthesizer can be implemented using waveguide Mach-Zehnder modulator technology. This device can provide any desired linear transformation of spatial modes between its inputs and its outputs. This capability can be generalized to any linear transformation at all by using representation converters to convert other quantities (e.g., polarization, frequency) to spatial mode patterns. The wave combiner and wave mode synthesizer are also useful separately, and can enable applications such as self-adjusting mode coupling, optimal multi-mode communication, and add-drop capability in a multi-mode system.

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.

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.
