Electronically Switchable Bragg Gratings (ESBGs)
Foster-Miller, Inc.Waltham, MA
Innovation Electrically controlled diffractive
optical elements based on a novel polymer/liquid
crystal microdroplet composite were developed for
programmable optical interconnects and switchable
focus lenses.
  • Accomplishments
  • Developed techniques for switchable diffractive
    lenses.
  • Demonstrated applications to reading multi-layer
    optical disks.
  • Showed reconfigurable interconnect optical
    architectures for high-speed parallel
    computation.
  • Developed holographic lithography and fabrication
    methods for ESBG lenses, electrodes and packages.
  • Due to nanoencapsulation, ESBG lenses switch in
    50 µs, much faster than bulk liquid crystals.
  • Enables spectral imagers and other applications
    of diffractive optics to eliminate moving parts.
  • ESBG arrays are a new type of spatial light
    modulator for transforming laser beams into large
    numbers of reconfigurable states.
  • Commercialization
  • Promising applications in optical communication
    networks for cntrol of wavelength division
    multiplexed (WDM) systems.
  • Foster-Miller has invested 1M internally in
    patent costs, market research and IRD to further
    develop ESBG telecomm products.
  • ESBG technology is targeted for Foster-Miller
    spin-off commercialization.

using ESBGs
  • Government/Science Applications
  • U.S. Navy contracted for demonstration of
    spectral imager with no moving parts.
  • ESBG fiber optic switch components for WDM under
    consideration for Next Generation Internet
    (DARPA).
