High-Speed Wavelength-Scale Spatial Light Modulators with Two-Dimensional Tunable Microcavity Arrays

Номер: US20210018767A1
Автор: Cheng Peng, Christopher Louis Panuski, Dirk Robert Englund, Ryan HAMERLY
Принадлежит: Individual

A reflective spatial light modulator (SLM) made of an electro-optic material, such as barium titanate, in a one-sided Fabry-Perot resonator can provide phase and/or amplitude modulation with fine spatial resolution at speeds over a Gigahertz. The light is confined laterally within the electro-optic material/resonator layer stack with microlenses, index perturbations, or by patterning the layer stack into a two-dimensional (2D) array of vertically oriented micropillars. Alternatively, a photonic crystal guided mode resonator can provide vertical and lateral confinement of the resonant mode. In phase-only modulation mode, each pixel in the SLM can produce a π phase shift under a bias voltage below 10 V, while maintaining nearly constant reflection amplitude. The methodology for designing this SLM could also be used to design other SLMs (for example, amplitude-only SLMs). This high-speed SLM can be used in a wide range of new applications, from fully tunable metasurfaces to optical computing accelerators, high-speed interconnects, true 2D phased array beam steering, beam forming, or quantum computing with cold atom arrays.

A color changing or beam steering photonic device, which combines a high contrast metastructure (HCM) having a plurality of high index grating structures, into a low index membrane. In response to physical (or electrical) deformation of the membrane the low index gaps between adjacent grating bars changes which results in changing reflectance and transmission angles for steering a single wavelength of light and for causing a color change in said photonic device when subject to multiple light wavelengths. Deformation can result from direct physical stimulus, conversion from electrical or thermal to physical, and so forth. Refractive index change can also be initiated by carrier injection through electrodes.

Автор: Ninan Ajit, Wan Chun Chi
Принадлежит: DOLBY LABORATORIES LICENSING CORPORATION

Techniques for driving a dual modulation display include generating backlight drive signals to drive individually-controllable illumination sources. The illumination sources emit first light onto a light conversion layer. The light conversion layer converts the first light, such as blue or ultraviolet light, into second light, such as white light. The light conversion layer can include quantum dot materials. Liquid crystal display (LCD) modulation drive signals are generated to determine transmission of the second light through individual color subpixels of the display. These LCD modulation drive signals can be adjusted based on one or more light field simulations to account for non-uniform, spatial color shifts. Alternatively, one or more light field simulations based on a uniformity assumption determine intermediate LCD modulation drive signals. A compensation field simulation, using backlight drive signals, is then used to adjust the intermediate LCD modulation drive signal for color correction. 1. A method for driving a display comprising:emitting first light by one or more illumination sources onto a quantum dot layer;converting the first light into second light by the quantum dot layer;determining intermediate display modulation drive signals by one or more light field simulations;determining a compensation field for spatial color non-uniformity related to traveling distances of light from the one or more illumination sources; andcompensating for the spatial color non-uniformity by adjusting the intermediate display modulation drive signals.2.
