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 ...
Hybrid Graphene/Gold Plasmonic Fiber-Optic Biosensor
A 2D material/metal hybrid plasmonic sensor is demonstrated by direct integration of graphene layer on gold-coated optical fiber. Both linear response to wide range ssDNA concentration from 1 × 10−12 to 10 × 10−6m and low ...
Widely tunable Tm-doped mode-locked all-fiber laser
We demonstrated a widely tunable Tm-doped mode-locked all-fiber laser, with the widest tunable range of 136 nm, from 1842 to 1978 nm. Nonlinear polarization evolution (NPE) technique is employed to enable mode-locking and ...
Exceptional points in a non-Hermitian topological pump
We investigate the effects of non-Hermiticity on topological pumping and uncover a connection between a topological edge invariant based on topological pumping and the winding numbers of exceptional points. In Hermitian ...
Efficient phase-matched third harmonic generation from mid-IR to near-IR regions in a double asymmetric plasmonic slot waveguide
Recent years, the research of mid-infrared (mid-IR) photonics has inspired increasingly interest due to their potential applications in a wide variety of areas, including free-space communications, chemical or biological ...
Simple and compact reflective refractometer based on tilted fiber Bragg grating inscribed in thin-core fiber
A simple and compact reflective refractometer based on a tilted fiber Bragg grating (TFBG) inscribed in an ultra-high photon-sensitive thin-core fiber is proposed and experimentally demonstrated. The reflective refractometer ...
Erbium-doped Fiber Laser with Distributed Feedback from a Fiber Grating Array
An erbium-doped fiber laser with low coherence, low threshold, high efficiency and narrow linewidth is demonstrated for the first time based on distributed feedback from a fiber Bragg grating (FBG) array. The FBG array ...
