In Situ characterization of the proton enhanced conductivity of 20nm TiO2 thin-films obtained on the surface of optical fiber
Jacob L. Poole, Paul R. Ohodnicki, Yang Yu +3
We report in situ characterized TiO2 thin-films deposited on optical fiber, having thicknesses in the 20-100nm range, and having enhanced conductivity values of 700S/cm upon intera…
Continuously tuning the refractive indices by restructuring materials on the 20-1000 atoms scale: improving anti-reflection coating designs
Jacob Poole, Aidong Yan, Paul Ohodnicki +1
We demonstrate the capability of block-copolymer templating to tune the refractive indices of functional oxides over a broad range by structuring materials on the 20-1000 atoms sca…

Integration of nanoporous materials such as metal organic frameworks (MOFs) with sensitive transducers can result robust sensing platforms for monitoring gases and chemical vapors…
Probing the Hydrogen Enhanced Near-Field Emission of ITO without a Vacuum-Gap
Jacob L. Poole, Yang Yu, Paul R. Ohodnicki
Thermal fluctuations of charged particles, fluctuations akin to Brownian motion, can excite optical surface-states leading to the concept of the thermal near-field, which is a high…
Near-Field Thermal Energy Conversion by Tunneling to a Waveguide
Jacob L. Poole, Paul R. Ohodnicki
Energy is a vital resource and hence there is a continuous strive to improve upon existing technologies and to find new ones that address that basic need. The conversion of thermal…
Sub-cm Resolution Distributed Fiber Optic Hydrogen Sensing with Nano-Engineered TiO2
Zsolt Poole, Paul Ohodnicki, Aidong Yan +2
The 3D nano-structuring on the <10nm scale allows the refractive index of functional sensory materials(n>2) to be reduced and matched with the cladding of optical fiber(n~1.46) for…
The optical applications of 3D sub-wavelength block-copolymer nanostructured functional materials
Zsolt Poole, Aidong Yan, Paul Ohodnicki +1
A method to engineer the refractive indices of functional materials (TiO2, ZnO, SnO2, SiO2), by nanostructuring in the deep sub-wavelength regime (<20nm), is presented. Block-copol…
