A network switch system includes a switch box and an optical communication device. The optical communication device includes a housing, a first light emitter disposed in the housing, a TOSA component set selectively disposed in the housing or within the switch box, and a ROSA disposed in the switch box. The first light emitter is optically coupled to the ROSA.

A 3D optical switch for transferring an optical signal between a plurality of layers of an optical integrated circuit, which comprises: a first optical coupler for distributing the optical signal input to a first optical waveguide deployed in a first layer among the plurality of layers to a second optical waveguide deployed in a second layer different from the first layer; a phase shifter for changing a phase of a first optical signal in the first optical waveguide passing through the first optical coupler and a phase of a second optical signal in the second optical waveguide distributed by the first optical coupler; and a second optical coupler for combining the first optical signal of which the phase is changed and the second optical signal of which the phase is changed is provided.

An M×N wavelength selective switch (WSS), may comprise a common port fiber array unit (FAU) configured to emit optical beams with a lateral offset and a beam steering device configured to direct optical beams with an angular offset to add/drop port optical fibers of an add/drop port FAU. The common port FAU may comprise a first set of common port optical fibers arranged in a first column of the common port FAU and a second set of common port optical fibers arranged in a second column of the common port FAU. The second column of the common port FAU may be laterally offset from the first column of the common port FAU. The beam steering device may be configured to selectively direct, in two dimensions, the optical beams with the angular offset to the add/drop port optical fibers.

An optical device includes an array of lenses and a plurality of segments disposed under the array of lenses. The plurality of segments corresponds to a plurality of images. Upon tilting the device at different viewing angle, the array of lenses presents images sequentially. In some examples, individual ones of the segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the segments can comprise transparent and non-transparent regions. Some examples can incorporate more than one region producing an optical effect.

Aspects of the present disclosure describe large scale steerable optical switched arrays that may be fabricated on a common substrate including many thousands or more emitters that may be arranged in a curved pattern at the focal plane of a lens thereby allowing the directional control of emitted light and selective reception of reflected light suitable for use in imaging, ranging, and sensing applications including accident avoidance.

An optical assembly includes a connector assembly, a plurality of port assemblies, and a frame assembly. The connector assembly includes an optical fiber connector. The plurality of port assemblies is fixed in position relative to each other. The frame assembly includes a frame directly attached to the connector assembly or directly attached to the plurality of port assemblies. The frame is moveable to align the connector with each of the port assemblies. The connector is insertable into each of the port assemblies when the connector is aligned with a respective one of the port assemblies by moving the connector or the respective port assembly aligned with the connector along a single axis and into the respective port assembly.

An optical cross apparatus including a single-row fiber array, and a single-row input multidimensional output optical waveguide element, where the single-row fiber array is coupled to the single-row input multidimensional output optical waveguide element, and an arbitrarily curved spatial three-dimensional waveguide is generated inside the single-row input multidimensional output optical waveguide element, and where a coupling surface of the single-row fiber array is the same as that of the single-row input multidimensional output optical waveguide element.

A method of aligning optical signals in a fiber optic switching device with one or two phase light modulators (PLMs) includes configuring the phase elements of the PLMs with first initial settings, to direct an optical signal from an input fiber to an output fiber. An initial position displacement of a center of the signal image from a center of the output fiber is estimated. Corrected settings for the phase elements are calculated so that when the corrected settings are applied to the phase elements, a corrected signal image of the optical signal has a corrected position displacement from the center of the output fiber that is less than the initial position displacement. A fiber optic switching device has processing circuitry and a memory component configured to execute steps of the method of aligning the optical signals.
