Abstract: A display system includes an optical light source and a display panel with an array of optically excitable pixels. Optics are positioned between the optical light source and the display panel so as to direct light from the optical light source toward the display panel to cause the optically excitable pixels to emit a visible image.

Abstract: A new class of vertical-cavity lasers (VCLs) is disclosed. Conventional VCLs contain an active region enclosed by Bragg-mirror stacks of 30-100 quarter-wave layers. The new VCLs can be fabricated without Bragg mirrors by replacing them with efficient diffractive (guided-mode resonance (GMR)) mirrors with much fewer layers, for example, two or three layers. This application provides optical power flow across and along the VCL gain region, thereby greatly increasing the laser efficiency and reducing the threshold mirror reflectance needed for lasing, relative to conventional VCLs. Theoretical and experimental results show that GMR mirrors exhibit high reflectance (theoretically, 100%; experimentally, in excess of 90%) in a narrow spectral band with well-defined polarization states. When incorporated in VCLs, the GMR mirrors yield single-mode, narrow-line, highly-polarized output light. The GMR-VCL is independent of any particular material system.
