Aspects and embodiments are generally directed to optical systems, receivers, and methods. In one example, an optical receiver includes a plurality of fused fiber optic bundles, at least a first fused fiber optic bundle of the plurality of fused fiber optic bundles positioned to collect optical radiation from a scene, a multi-mode fiber optic cable coupled to each fused fiber optic bundle of the plurality of fused fiber optic bundles, the multi-mode fiber optic cable configured to propagate the collected optical radiation from each of the plurality of fused fiber optic bundles along a length of the multi-mode fiber optic cable, and a photo-detector coupled to the multi-mode fiber optic cable and configured to receive the collected optical radiation. A field of view of each fused fiber optic bundle of the plurality of fused fiber optic bundles may collectively define a substantially omnidirectional field of view of the photo-detector.

A deformable mirror and capacitive array controller is capable of controlling a plurality of individual actuators by applying independent voltages from 0V to 240V to each actuator. The device utilizes a distributed microcontroller (MCU) architecture, including a main microcontroller and a plurality of slave microcontrollers to maximize actuator voltage refresh rate. One Slave MCU may be used for up to 384 actuators. For maximizing actuator refresh rate, each Slave MCU may be limited to 192 actuators. The final circuit stage includes a digital/analog converter, a voltage sample and hold and a high voltage amplifier, all packaged in a single integrated circuit. These integrated circuits are referred hereinafter as HV S&H (high voltage sample and hold). A flexible, stacked PCB assembly significantly reduces overall footprint and weight compared to conventional devices. The device's power consumption is nearly an order of magnitude less than that of a conventions adaptive optical system.

Techniques for creating an SiGe/Si electro-optomechanical quantum transducer, comprising an SiGe/Si optical ring resonator and capacitor, that can be associated with a qubit are presented. The optical resonator, comprising an SiGe optical waveguide and a strained silicon membrane, can be formed and disposed over a substrate. The strained silicon membrane can have a photoelastic coupling with the SiGe optical waveguide. A capacitor, comprising a superconducting material, can be formed in proximity to the optical resonator. The top plate of the capacitor can be associated with the strained silicon membrane. A recessed region can be formed in the back side of the substrate along a desired silicon plane, extending to form a hole in the top side of the substrate. A superconducting material can be applied along substrate surfaces defining the recessed region and hole. The superconducting material covering the hole can be the bottom plate of the capacitor.

Integrated optical component combine the functions of a Variable Optical Attenuator (VOA), a tap coupler, and a photo-detector, reducing the size, cost, and complexity of these functions. In other embodiments, the integrated optical component combines the functions of an optical switch, a tap coupler, and a photo-detector. A rotatable mirror is used to adjust the coupling of light from an input port or ports to one or more output ports. A pin hole with a surrounding reflective surface is used at the core end face of one or more output fibers, such that a portion of the output optical signal is reflected to a photodiode chip. The photo-detector provides an indication of the optical power that is being coupled to the output fiber. With appropriate electronic control circuitry, the integrated optical component can be used to set the output optical power at a desired or required level.

An optical silicon beam-steering apparatus made from one or more silicon wafers. The apparatus includes a bonded stack of one or more wafers including a mirror wafer and a possibly distinct wafer for actuation which allows the device to achieve a large scan range, a large mirror size and a high scan frequency.

A splice module includes a main splicing channel and a rework channel. The main splicing channel has an encapsulated section at which one or more initial splices can be stored. The main splicing channel also includes a non-encapsulated section through which trunk cable fibers of the initial splices extend. If re-splicing is needed, the trunk cable fibers can be accessed at the non-encapsulated section, cut, and re-spliced to a new connectorized pigtail or other optical fibers.

In some embodiments, a photonic switch includes a first layer, a cantilever coupler, and a set of electrodes. The first layer includes a first waveguide that directs light in a first direction and a second waveguide that directs light in a second direction that is different from the first direction. The cantilever coupler is formed from a lithium niobate material and disposed over the first layer. The cantilever coupler includes a first end that is positioned over the first waveguide and a second end that is bonded to the second waveguide. The set of electrodes apply an electric potential across the first end, which deforms the first waveguide to couple to the second waveguide and propagates light between the first waveguide and the second waveguide.

The movable portion is supported by a first end of the support portion. A second end of the support portion is supported by the substrate portion. An end of the movable portion is capable of coming into contact with the substrate portion. The reflective portion is formed on the movable portion. The moving mechanism is capable of driving the movable portion so as to bring the movable portion into at least any one of a first state, a second state, a third state, and a fourth state.
