Abstract: A laser includes an active ring, a passive waveguide, and a reflector. The active ring is to generate light. The passive waveguide is associated with the active ring to capture generated light. The reflector is associated with the passive waveguide to cause captured light from the waveguide to be coupled into the active ring to trigger domination of unidirectional lasing in the active ring to generate light.

Abstract: According to an example, a display-camera system includes a transparent display panel and a transparent backlight panel. Light sources emit light into the edge of the transparent backlight panel. A first polarizer, between the light sources and the edge of the transparent backlight panel, polarizes the light emitted from the light sources and the transparent backlight panel directs the polarized light towards the transparent display panel. A camera, adjacent a back surface of the transparent backlight panel captures an image of a scene through the transparent display panel and the transparent backlight panel.

Abstract: An example apparatus may include a light source for illuminating a sample, an objective lens positioned on a light path extending from the sample, a lenslet array having a plurality of lenslets and positioned along the light path to receive light from the objective lens. The lenslet array may be positioned along the light path at substantially a Fourier plane of the sample. The example apparatus may also include a detector positioned along the light path approximately one lenslet focal length from the lenslet array. The plurality of lenslets of the lenslet array may correspond to portions of the detector. Each lenslet of the lenslet array may transmit to a corresponding portion of the detector an image of the same portion of the sample from a different viewing angle.

Abstract: A mode-controlled laser system includes an active region to generate optical energy in response to an electric signal. The system also includes a mirror to resonate the optical energy in an optical cavity. The system also includes a HCG mode control reflector arranged in the optical cavity to control the resonated optical energy into a substantially non-Gaussian intensity profile. The resonated optical energy can be emitted as an optical signal having the substantially non-Gaussian intensity profile.

Abstract: A backlight includes a plate light, guide to guide light, a light source to produce light, and a collimating reflector to substantially collimate the produced light. The collimating reflector also is to direct that collimated light into the plate light guide as guided light of the plate light guide. A portion of the guided light in the backlight is to be emitted from a surface of the backlight as emitted light.
