An integrated tunable waveguide element includes: a cladding. A high k dielectric layer is disposed within the cladding. At least one waveguide is disposed adjacent to the high k dielectric layer. At least one two dimensional monolayer pad is disposed on or in the high k dielectric layer adjacent to a portion of the at least one waveguide. An integrated 2×2 array element is also described.

An optical circuit switch including a two-dimensional fiber collimator includes a hole plate to hold and align a plurality of optical fibers. Fiber pathways within the hole plate can be formed using a femtosecond laser irradiation chemical etching (FLICE) technique. The use of the FLICE technique allows for extremely precise channels to be formed which allows for fibers to be aligned more closely with their intended alignment. The technique also allows for the channels or fiber pathways to be formed in a thicker material, which allows for greater structural support and robustness of the fiber collimator in use.

An optical assembly includes a light source for providing a beam of light, a lens system configured to expand and collimate the beam of light, and a configurable beam injector, wherein the beam injector contains a first grid plate and a second grid plate to block individual beams of light. The first grid plate and the second grid plate may be configured such that each grid plate respectively corresponds to particular MEMS mirrors. The grid plates can be configured to have pathways that allow for beams of light to be passed through and other pathways which are blocked to prevent the passage of light. The first grid plate and second grid plate may thus block or allow for transmission of beams of lights to those particular MEMS mirrors. The second grid plate can be configured to be easily swappable during or removable to allow for a different set of beams of light, corresponding to a different set of MEMS mirrors, to be blocked. The second grid plate can be configured to be rotated or slid linearly within a housing.

A system or method for a magnetic self-aligning coupling device for a fiber optic cable. The device includes a first end coupling comprising a first magnet and a second magnet. Both magnets include a mating surface and an annular ring defining an axial aperture. The aperture receives a distal end of a segment of fiber optic cable in a tight fit. The fiber optic cable has an exterior sleeve and a fiber core. The fiber core of the first segment and the second segment of the fiber optic cable are axially aligned by magnetic force in the first and second apertures to create a continuous fiber optic path. A method for detecting a security breach of a door using the self-aligning couplings is also described.

Wavelength division multiplexing (WDM) has enabled telecommunication service providers to provide multiple independent multi-gigabit channels on one optical fiber. To meet demands for improved performance, increased integration, reduced footprint, reduced power consumption, increased flexibility, re-configurability, and lower cost monolithic optical circuit technologies and microelectromechanical systems (MEMS) have become increasingly important. However, further integration via microoptoelectromechanical systems (MOEMS) of monolithically integrated optical waveguides upon a MEMS provide further integration opportunities and functionality options. Such MOEMS may include MOEMS mirrors and optical waveguides capable of deflection under electronic control. In contrast to MEMS devices where the MEMS is simply used to switch between two positions the state of MOEMS becomes important in all transition positions. Improvements to the design and implementation of such MOEMS mirrors, deformable MOEMS waveguides, and optical waveguide technologies supporting MOEMS devices are presented where monolithically integrated optical waveguides are directly supported, moved and/or deformed by a MEMS.

The switching array includes a plurality of switching optical amplifiers configured to amplify a laser signal of the plurality of input laser signals as an amplified laser signal and absorb the remaining of the plurality of input laser signals.

An information handling system may include a processor and a plurality of ports communicatively coupled to the processor, and physically arranged in a first row and a second row at an exterior panel of an enclosure of the information handling system, such that the plurality of ports includes front ports of the first row visible when the exterior panel is viewed head on, rear ports of the first row located directly behind the front ports of the first row from a perspective in which the exterior panel is viewed head on, front ports of the second row visible when the exterior panel is viewed head on, and rear ports of the second row located directly behind the front ports of the second row from the perspective in which the exterior panel is viewed head on.

The laser-induced dispensing system includes a cartridge assembly having a supply reel for supplying a foil having a light transmissive layer wound around the supply reel, and a take-up reel for taking up the foil. There is provided a coating device for coating the foil by a donor material during a motion of the foil. The laser-induced dispensing system also includes an irradiation head having optics configured for focusing a laser beam. Additionally, a controller, for controlling the cartridge assembly to establish motion of the foil, and the optics to focus the laser beam onto the foil at a location downstream of the outlet of the coating device so as to release droplets of the donor material from the foil is provided.

A projector includes an illumination waveguide layer, a collimation waveguide layer, and a spatial modulator. The illumination waveguide layer expands a light beam which is coupled to the spatial modulator. The spatial modulator modulates the expanded light beam to provide a line of light points of controllable brightness. The collimation waveguide collimates light of the light points to obtain a fan of collimated light beams. Each collimated light beam of the fan has an angle corresponding to a coordinate of the corresponding light point of the line. A tiltable reflector may be placed at the exit pupil to scan the fan of light beams in a plane non-parallel to the plane of the fan, thus providing a 2D image in angular domain. An array of Mach-Zehnder interferometers may be used in place of the illumination waveguide layer and the spatial modulator to provide the line of light points.

Cladding removed from a portion of the optical fiber defines a window exposing the fiber core. A grating having a substantially periodic structure defining a wavelength is moveably positioned in the window, where it can interact with the evanescent field present in the window when optical power is propagating through the fiber. An adjustable positioning fixture holds the grating proximate to the window and operates to change the relative spacing of the fiber core and grating, between: a first position in which the grating is held proximate to the fiber core and substantially interacts with the evanescent field, and a second position in which the grating is held apart from the fiber core and does not substantially interact with the evanescent field.
