A module handles beams having multiple channels in an optical network. The module has a dispersion element, a liquid crystal (LC) based switching assembly, and photodetectors. The dispersion element is arranged in optical communication with the beams from inputs and is configured to disperse the beams into the channels across a dispersion direction. The switching assembly is arranged in optical communication with the channels from the dispersion element and is configured to selectively reflect the channels using electrically switchable cells of one or more LC-based switching engines. The photodetectors are arranged in optical communication with the dispersion element, and each are configured to receive selectively reflected channels for optical channel monitoring. Outputs can be arranged in optical communication with the dispersion element and can be configured to receive selectively reflected channels for wavelength selective switching.

An augmented reality (AR) display apparatus includes an outputter that outputs first radiation including visual information in a predetermined spectrum, a polarizing plate that absorbs a first s-polarized radiation from the first radiation and transmits a first p-polarized radiation and an optical layer that reflects at least a portion of the first p-polarized radiation incident on a first side of the optical layer with a wavelength corresponding to the predetermined spectrum.

A system can direct light into an optical fiber. Imaging optics can form an image of an end of an optical fiber. An actuatable optical element can be configured to define an optical path that extends to the actuatable optical element and further extends to the end of the optical fiber. A processor can determine a location in the image of a specified feature in the image. The processor can cause, based on the location of the specified feature in the image, the actuatable optical element to actuate to align the optical path to a core of the optical fiber. A light source can direct a light beam along the optical path to couple into the core of the optical fiber.

An active mode image sensor for optical non-uniformity correction (NUC) of an active mode sensor uses a Micro-Electro-Mechanical System (MEMS) Micro-Mirror Array (MMA) having tilt, tip and piston mirror actuation to form and scan a laser spot that simultaneously performs the NUC and illuminates the scene so that the laser illumination is inversely proportional to the response of the imager at the scan position. The MEMS MMA also supports forming and scanning multiple laser spots to simultaneously interrogate the scene at the same or different wavelengths. The piston function can also be used to provide wavefront correction. The MEMS MMA may be configured to generate a plurality of fixed laser spots to perform an instantaneous NUC.

An aspect relates to an optical limiter (200) for limiting the radiant flux of an optical source beam, comprising: an optical control port (221) for illumination by an optical control beam originating from the source beam; an optical input port (221) for illumination by an optical transmission beam originating from the source beam; an optical output port (225) for illumination by the transmission beam; and a thermally driven light mill (211, 212); wherein the light mill is arranged with respect to the input port, the control port and the output port such that illumination of the control port by the control beam drives the light mill to rotate only when the control beam has a radiant flux equal to or in excess of a predetermined radiant flux threshold; and rotation of the light mill causes an area of the output port illuminated by the transmission beam to change.

An optical waveguide at least includes: a lower clad layer; a core that is disposed on the lower clad layer and includes an entrance plane and an emission plane; and an optical path converting mirror including an inclined surface that is neither in parallel with nor orthogonal to a plane formed by the lower clad layer. The core includes a restriction release plane. When one of two portions obtained by dividing the core in two at the restriction release plane that is on the side of the entrance plane is defined as a first core pattern portion and remaining one of the two portions on the side of the emission plane is defined as a second core pattern portion, the optical path converting mirror is disposed on an optical path of the first core pattern portion or an extension of the optical path. At least a part of the light that has entered through the entrance plane is reflected by the optical path converting mirror to have an optical path converted. At least a part of light with an optical path not converted to be in a substantially orthogonal direction is emitted from the emission plane.

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.
