Abstract: This disclosure describes a glucose monitor with one or more photonic crystal surface-emitting lasers (PCSELs). The PCSEL comprises a plurality of photonics crystal sections. Each photonics crystal section is operable to emit light of a different wavelength. The horizontal emission by each photonics crystal section may be constrained by edge lattice sections.

Abstract: A semiconductor laser assembly includes an array of surface emitting lasers having a light emitting surface and an opposing surface; at least one electrical contact electrically connected to provide to the array of surface emitting lasers an electrical bias from an external electrical source; and an optical waveguide over the light emitting surface. The optical waveguide includes lithium.

Abstract: A display system includes a display screen layer, a coupling region, an upper guide, a first coupler, a second coupler, and an optical element. The coupling region may be positioned along a sidewall of the display screen layer and may route a beam between the optical element and the upper guide and may route the beam between the first coupler and the second coupler. The first coupler may be positioned along a front surface of the upper guide and may couple a beam through the front surface of the upper guide. The second coupler may be positioned between the coupling region and the upper guide and may couple the beam between the coupling region and the upper guide. The optical element may be positioned below a back surface of the upper guide. A computing device with the display system is also disclosed.

Abstract: This disclosure describes a bottom surface emitting vertical cavity surface emitting laser (BSE VCSEL) with a lithographically defined aperture. The BSE VCSEL may be oxide-free. Two contacts are located above a substrate. An aperture and one or more active regions are located between two DBRs. A first contact is coupled to the substrate and the first DBR, which is below the aperture. A second contact is coupled to the second DBR, which is above the aperture.

Abstract: Systems and methods are provided for optical source assemblies for use with organic light-emitting diode (OLED) based screens for mobile applications. A screen having one or more layers may be used in conjunction with a plurality of optical source assemblies embedded within or behind the screen, with the plurality of optical source assemblies configured to emit beams at certain locations within the screen, and where at least one of the one or more layers is configured to adjust or affect diffractive characteristics of beams emitted by the plurality of optical source assemblies. The screen may be an OLED based screen. The layers may include a thin-film-transistor (TFT) layer and an OLED layer. The TFT layer and/or the OLED layer may be configured to multiply emitter count on a projected area, and/or to shape emitter count and/or properties.

Abstract: Sensors with an addressable depth range and/or field of view are disclosed. Computing devices with such sensors are also disclosed. A sensor may include multiple output couplers that are positioned at different distances from a receiver. Through selective enabling of the output couplers, light or other radiation generated by a transmitter may be directed toward the output couplers and selectively emitted from the sensor at different distances from the transmitter. Such selective emitting may adjust a depth range and/or field of view of the sensor. A computing device may include a single sensor that is used across applications and/or processes having different needs with regard to depth range and/or field of view.

Abstract: This disclosure describes a red-green-blue (RGB) vertical-cavity surface-emitting laser (VCSEL) array. Each VCSEL in the VCSEL array has a grating, one or more active regions and two distributed Bragg reflectors. Each VCSEL corresponds to either red, green or blue wavelengths. The number of active regions in each VCSEL may be based on the color emitted.

Abstract: This disclosure describes a vertical-cavity surface-emitting laser (VCSEL) structure with a locked polarization and collimating optical element. The VCSEL structure comprises a grating, an optical emitter such as a lens and a plurality of GaAs/AlGaAs mirrors between the grating and the optical emitter. The grating located between the mirror stacks and above or below the active region is able to polarize incident waves of the VCSEL structure.
