Dynamic Holography and Fiber Optics

• Atomic force microscopy electrostatic nanolithography (AFMEN). Together with scientists at USAF Research Laboratory we invented the AFMEN (3 US Patents: – a versatile tool to pattern at the nanoscale dielectric or semiconducting thin films (polymers, viruses, graphene fluoride, styrene butadiene, CdS, p-Si pretreated with organic solvents, etc.). The AFMEN established a new paradigm for nanolithography allowing rapid (~ 3ms) creation of nanostructures.  

• Fiber Bragg gratings analysis. There is a substantial interest to use the FBGs as sensors in aerospace applications due to their small size, high bandwidth, and immunity to extreme environments. That interest has triggered a need to understand the physics of the FBGs’ performance at extreme temperatures of up to 1000 K and above and also at another end of thermal spectrum, low temperatures when conditions are close to deep vacuum. We developed a technique to measure precisely thermo optics coefficient in FBG silica-based sensors (Collaborative effort with NASA Glenn).

• Dynamic holography and space charge waves in photorefractive materials. We have derived a closed-form solution of band-transport model (The Kukhtarev equations) for high-contrast gratings in photogalvanic crystals. The space-charge waves are common in physics and plasma and semiconductors. We report experimentally the space charge waves in photorefractive materials with point group 23.
