This technology is an integrated metasurface which can generate a free-space optical wavefront with specific optical properties. Therefore, current technologies are unable to control more than two disparate elements of light at the same time, including properties such as polarization, amplitude, and phase. This design enables the independent control of four optical parameters including amplitude, phase, polarization orientation and polarization ellipticity.
This technology is a suite of optical components that can control incoming light signals with high precision and without distortion, potentially leading to breakthroughs in virtual reality glasses, LIDAR systems, chemical spectrometers, holographic displays, and more. The Technology: Optical components that precisely control incoming light signals without distortion. This technology is a class of optical components used for controlling light signals.
Traditional methods for trapping ultracold atoms, like optical lattices using acoustic optical diffractors and spatial light modulators, are limited by large device footprints, high power and cooling requirements, and inflexibility in the control of trap geometries. The Technology: Compact, scalable optical trapping using metasurfaces. Metasurfaces, composed of a 2D array of nanostructured elements, manipulate the amplitude, phase, and polarization of light across the wavefront with subwavelength resolution, enabling the creation of complex, high-density trap geometries.
