Ultra-sensitive chemical and biological analysis via specialty fibers with built-in microstructured optofluidic channels
All-in-fiber optofluidics is an analytical tool that provides enhanced sensing performance with simplified analyzing system design. Currently, its advance is limited either by complicated liquid manipulation and light ...
Formation of ultra-flexible, conformal, and nano-patterned photonic surfaces via polymer cold-drawing
We report a lithography-free method for large-area plasmonic nano-patterning on ultrathin plastic films through a polymer cold-drawing process. We further transfer the ultra-flexible nano-patterned films onto the curved ...
Review on photonic crystal fibers with hybrid guiding mechanisms
Photonic crystal fibers (PCFs) with hybrid guiding mechanisms have undergone substantial development in recent years. Due to the co-existence of index-guiding and photonic bandgap (PBG)-guiding mechanisms in this special ...
Using nonlinear optical networks for optimization: primer of the ant colony algorithm
Using nonlinear Erbium doped optical fiber network we have implemented an optimization algorithm for the famous problem of finding the shortest path on the map for the ant colony to travel to the foraging area.
Ultrathin graphene diaphragm-based extrinsic Fabry-Perot interferometer for ultra-wideband fiber optic acoustic sensing
An ultra-wideband fiber optic acoustic sensor based on graphene diaphragm with a thickness of 10nm has been proposed and experimentally demonstrated. The two reflectors of the extrinsic Fabry-Perot interferometer is consist ...
Theoretical study of bicharacteristic waveguide for fundamental-mode phase-matched SHG from MIR to NIR
In this paper, a bicharacteristic waveguide (BW) is proposed for fundamental-mode phase-matched second harmonic generation (SHG) from mid-infrared (MIR) to near-infrared (NIR). The required phase matching condition (PMC) ...
Volumetric enhancement of Raman scattering for fast detection based on a silver-lined hollow-core fiber
Fast detection and identification of chemicals are of utmost importance for field testing and real-time monitoring in many fields. Raman spectroscopy is the predominant technique in principle, but its wide application is ...
