Michael Escuti, ECE Department, NC State University
Michael Escuti has been awarded $150,420 by Boulder Nonlinear Systems for research on SBIR Phase II Wide-Angle Nonmechanical Steering Development.
The award will run from October 16th, 2007 to October 15th, 2009.
Research Abstract - For the purposes of this proposal, my university lab at NCSU will provide Boulder Nonlinear Systems (BNS) with large-area polarization gratings (5 cm aperture) for beam-steering, including both switchable and polymerized versions. These will be optimized for a near-infrared wavelength (1.5 microns), have diffraction efficiency of 95% or greater into a single order, have low insertion loss (e.g. less than 5%), and be arranged to diffract into the following angles: 1.25 degrees, 2.5 degrees, 5 degrees, 10 degrees, and 20 degrees. Uniformity and cleanliness will be a top priority, with an objective to have high diffraction over the entire aperture with a variation of less than 2%. All work will be done in close collaboration with BNS, and the number of final delivered gratings will be somewhere between 20 to 40 gratings, and will depend on the testing of the multiple approaches in the first year.
