Antenna on a Chip Zips Through 3-D ‘Free Space’

Facebook X LinkedIn Email
HOUSTON, Nov. 21, 2012 — A new micron-scale spatial light modulator (SLM) works in 3-D “free space” and runs orders of magnitude faster than those used in sensing and imaging devices, and it holds great potential for imaging, display, holographic, measurement and remote sensing applications. The “antenna on a chip” device, developed at Rice University, looks like a tiny washboard and could make current commercial products used to manipulate infrared light obsolete. A new antenna on a chip for spatial light modulation enables the manipulation of infrared light at very high speeds...Read full article

    cavity
    In a laser, the optical resonator formed by two coaxial mirrors, one totally and one partially reflective, positioned so that laser oscillations occur.
    holography
    Holography is a technique used to capture and reconstruct three-dimensional images using the principles of interference and diffraction of light. Unlike conventional photography, which records only the intensity of light, holography records both the intensity and phase information of light waves scattered from an object. This allows the faithful reproduction of the object's three-dimensional structure, including its depth, shape, and texture. The process of holography typically involves the...
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    remote sensing
    Remote sensing is a method of data collection and observation where information about objects, areas, or phenomena on Earth's surface is gathered from a distance, typically using sensors onboard satellites, aircraft, drones, or other platforms. This technique enables the monitoring and analysis of Earth's surface and atmosphere without direct physical contact. Remote sensing systems capture electromagnetic radiation (such as visible light, infrared, microwave, or radio waves) reflected or...
    spatial light modulator
    A spatial light modulator (SLM) is an optical device that modulates or manipulates the amplitude, phase, or polarization of light in two dimensions, typically in the form of an array. SLMs are versatile tools used in various optical applications, including adaptive optics, optical signal processing, holography, and imaging. There are different types of SLMs, each with its own operating principle: Liquid crystal spatial light modulators (LC-SLM): These SLMs use liquid crystal technology to...
