Abstract
Diffraction gratings are powerful tools for the spectral analysis of electromagnetic radiation. Properties of gratings are determined by available fabrication means – which have not changed substantially in 50 years. Modern photolithography, now approaching nanometer resolution, may revolutionize the way many gratings are made and, through greater design flexibility, how gratings function. Over 1011 pixels, each smaller than 100 nm and collectively spanning areas of multiple centimeters, can be addressed individually with nanometer-scale absolute positioning accuracy by modern lithographic tools, thereby making it possible to create gratings with virtually any desired line curvature, variable line spacing, length and thickness – features largely beyond traditional fabrication means. LightSmyth Technologies proposes to leverage these state-of-the-art photolithographic patterning tools to design flat imaging gratings that combine dispersive grating function with one- and two-dimensional focusing. Importantly, diffractive, aka holographic, focusing may have substantially lower aberration in low f-number or high incidence angle configurations. Line spacing and curvature do the focusing. This design and fabrication strategy will be applied to the development of gratings for NASA's NEXUS effort and other advanced grating products of value to NASA and the commercial markets – all of which leverage on the innovative fabrication platform LightSmyth brings to the diffractive market.
