Proposed works provide a manufacturing path to produce precision large area diffraction gratings at affordable cost to end user. In general, any application that needs a large area diffraction grating with superb spectrum performance will be benefited from this development. In foreseeable future, military surveillance and guided weapon system will likely take benefits from this development. By adding a large area diffraction grating together with optical detector with arrayed pixels, it becomes possible to obtain target images within a narrow spectrum band. The narrow spectrum imaging and band selection capability will tremendously improve performance of target finding, tracking, and identification. This means fast, accurate, and reliable battlefield surveillance and smarter guided weapons. Most importantly, this development can produce large area diffractive gratings with superb spectrum band selection cheaply enough for broad implementations on battlefield. Security force is another potential user benefiting from this development. The key technology SPEL developed in proposed works will have tremendous impacts on nanofabrication when feature size variation control becomes more and more challenging for making nano-devices. Potentially, the key technologies used and developed for proposed manufacturing process can also be used for making other optical devices, nanofluidic channel for bio-applications, and nano-wire based sensors.
