PHASE-I CONTRACT: NAS5-01190
PROPOSAL TITLE: A switchable holographic circle to point converter for use in LIDAR receivers

TECHNICAL ABSTRACT (LIMIT 200 WORDS)
A solid state air-gap Fabry-Perot is configured in tandem with a switchable holographic optic element established by holographic polymer liquid crystal dispersion. This switchable element is the innovative centerpiece developed during Phase I research. By stacking these tuning elements, one per wavelength channel, any discrete channel within the operating range (which can include multiple orders) of a Fabry-Perot etalon can be selected for transmission to any receiver in a LIDAR or spectroscopy system. A sealed, solid state etalon combined with a switchable holographic element can replace a tunable etalon system. This has advantages with respect to LIDAR system cost, complexity and weight. Multiplexing allows additional spectral elements to be selected simultaneously or a channel may be switched in milliseconds. The device can thus isolate hundreds of individual wavelengths across the tunable range of a tunable laser or LIDAR transmitter. These capabilities are accomplished with no moving parts, and with a significant cost advantage over competing technologies.

POTENTIAL COMMERCIAL APPLICATIONS
The largest commercial market is telecommunications where this beam steering technology can be used to randomly switch signals among different fiber channels. A solid-state, dense, random optical cross-switch is commercialized to fill needs in the commercial metro-core telecom market, and to supply rapid, multi-channel, covert, and frequency agile optical communications to the national missile defense initiative. The optical switch is based upon Fabry-Perot and Holographic Polymer Dispersed Liquid Crystal (H-PDLC) technology. The deliverable is entirely solid state, is switched electronically requiring minimal power, and is fabricated using planar fabrication techniques - providing significant cost and durability advantages over competing technologies. Additionally this device when configured, as a solid state LIDAR receiver will result in many sales to the space based remote sensing community.
