    摘要: A fiber optic communications arrangement includes a closure with an interior volume; the closure including at least one cable through-port in communication with the interior volume; and an expansion component attached to an exterior portion of the closure and having an interior region in communication with the closure interior volume. The expansion component includes ruggedized fiber optic adapters mounted thereto. Each of the ruggedized fiber optic adapters includes at least one connector port for receiving ruggedized fiber optic connectors.

    摘要: Systems, devices, and methods for optical waveguides that are well-suited for use in wearable heads-up displays (WHUDs) are described. An optical device comprises an optical waveguide including a volume of optically transparent material having a first longitudinal surface positioned opposite a second longitudinal surface across a width of the volume, an in-coupler, a liquid crystal out-coupler, and a controller to modulate a refractive index of the liquid crystal out-coupler. Light is in-coupled into the waveguide and is propagated along a length of the waveguide by total internal reflection between the longitudinal surfaces before being out-coupled by the liquid crystal out-coupler on a path that is dependent on the modulated refractive index of the liquid crystal out-coupler. In this way, light signals can be steered to create an image and/or to move an exit pupil of an image. WHUDs that employ such optical waveguides are also described.

    摘要: To provide an optical transmitter module with simplified control of a voltage to be applied to an optical modulator. An optical transmitter module includes a semiconductor laser for irradiating a laser beam; a demultiplexer for branching the laser beam to output branched light beams; optical modulators for modulating an optical amplitude of each of the branched light beams into a first optical amplitude or a second optical amplitude, depending on an input level at two levels; and a multiplexer for multiplexing output light beams from the optical modulators. The optical transmitter module may include optical waveguides for connecting the optical modulators and the multiplexer, and the optical waveguides may include a first optical waveguide for causing a first phase difference and a second optical waveguide for causing a second phase difference different from the first phase difference.
