Higher-order topological pumping and its observation in photonic lattices
Wladimir A. Benalcazar, Jiho Noh, Mohan Wang +3
The discovery of the quantization of particle transport in adiabatic pumping cycles of periodic structures by Thouless [Phys. Rev. B 27, 6083 (1983)] linked the Chern number, a top…
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…
Topological protection of photonic mid-gap cavity modes
Jiho Noh, Wladimir A. Benalcazar, Sheng Huang +4
Defect modes in two-dimensional periodic photonic structures have found use in a highly diverse set of optical devices. For example, photonic crystal cavities confine optical modes…
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…
