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: 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.
