Harnessing oversampling in correlation-coded OTDR
Coding technique has long been investigated as a solution to improve the signal-to-noise ratio (SNR) without sacrificing spatial resolution in optical time domain reflectometry (OTDR) systems. The past researches have been ...
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 ...
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 ...
