A waveguide display for use in a near-eye display system includes a waveguide stack having at least one waveguide substrate, an input coupler coupling light into the waveguide substrate and an optical arrangement that includes a birefringent reflective polarizer, a mirror and a polarization state converting element configured to convert light in a linear polarization state to a circular polarization state and to convert light in a circular polarization state to a linear polarization state. The mirror is arranged to receive light from the polarization state converting element and reflect the light back to the polarization state converting element. The optical arrangement causes a transmission path of light that traverses the waveguide stack a first time to be folded back through the waveguide stack such that at least a portion of light not coupled into the waveguide substrate is caused to traverse the waveguide stack a plurality of additional times.

An optical article partially transmits polarized glare in tunable colors that help a user to see surface contours, while enhancing the color and at the same time maintaining the appearance of the lens still neutral.

A device includes a light source to emit light and a light detector to receive the light emitted by the light source. The device may include a high voltage optical transformer and may be configured such that the light detector is laterally spaced away from the light source. In some architectures, the light source and the light detector may be arranged in a common plane. A photonic integrated circuit may be used to couple light emitted from the light source to the light detector.

The housing includes a first passage that extends between a first opening and a second opening which are aligned with one another along a first axis, and a second passage that extends between the first passage and a third opening. The third opening is aligned with and communicatively coupled to the first passage along a second axis that is transverse to the first axis. The beam splitter assembly is positioned in the first section of the housing, and includes a first shell, a beam splitter platform, and a beam splitter. The polarizer assembly is positioned in the second section of the housing, and includes a second shell, a polarizer platform, and a polarizer.

Disclosed herein are methods, devices, and system for beam forming and beam steering within ultra-wideband, wireless optical communication devices and systems. According to one embodiment, a free space optical (FSO) communication apparatus is disclosed. The FSO communication apparatus includes a semiconductor optical device configured to have a transient response time of less than 500 picoseconds (ps), a lens, and a first band select filter.

A filtering vision element forming a windshield or rearview mirror of a road vehicle includes a lower region and an upper region. The filtering vision element is designed so that a difference in attenuation between two linear polarizations of an incident radiation has values that are of opposite signs in the lower and upper regions. The two linear polarizations may respectively be horizontal and contained in a vertical plane. Blinding of the driver caused by a spot of reflected light produced on a road by headlights of an external vehicle may thus be decreased or prevented.
