Experimental verification of higher-order mode suppression in a bent large-mode-area multi-cladding fiber
Fiber design and fabrication iber properties
2015/6/9
A novel technique to suppress the higher-order mode in a bent large-mode-area triple-cladding fiber is experimentally presented. 3-dB suppression of LP 02 mode is observed on a fabricated triple-cladd...
Simple suppression technique for higher-order mode amplification in bent large mode area triple-cladding fibers
Fiber design fabrication iber properties
2015/6/4
A novel technique to suppress the higher-order mode in bent LMA triple-cladding fibers is proposed. It is shown that the higher-order mode can be coupled to a cladding mode with only an adjustment of ...
Sectioned Core Doping Effect on Higher-Order Mode Amplification in Yb-Doped Rod-Type Photonic Crystal Fibers
Sectioned Core Doping Effect Higher-Order Mode Amplification Yb-Doped Rod-Type Photonic Crystal Fibers
2015/7/16
The amplification properties of guided modes in Yb-doped rod-type photonic crystal fibers with sectioned core doping have been investigated, evaluating the doped-area radius which provides the effecti...
Supercontinuum Generation by Higher-order Mode Excitation in a Photonic Crystal Fiber
Supercontinuum Generation Higher-order Mode Excitation Photonic Crystal Fiber
2015/7/16
Higher-order-mode excitation experiments are interesting because the anomalous dispersion region is shifted towards smaller wavelengths and because the existence of a cut-off wavelength generates spec...

Optical Demultiplexing Extinction Ratio Enhancement Based Higher Order Parametric Interaction
2015/7/14
We present the experimental demonstration of an all-optical demultiplexer for high speed OTDM data with optical regeneration capability. It is shown that higher order parametric interactions provide o...
Analysis of Double Rayleigh Scattering Noise in Higher-order Pumped Distributed Raman Amplifiers
Double Rayleigh Scattering Noise Higher-order Pumped Distributed Raman Amplifiers
2015/8/4
A theoretical analysis of double Rayleigh scattering (DRS) noise in higher-order Raman pumping schemes is presented. Simulations confirm an unexpected DRS noise decrease for pumping schemes above 3 rd...
DGD Estimation from FIR Filter Taps in Presence of Higher Order PMD
DGD Estimation FIR Filter Taps Higher Order PMD
2015/7/31
We estimate the DGD τ ( ω ) over the complete system bandwidth from FIR filter taps in coherent receivers with digital equalization, obtaining accurate DGD values even in presence of higher order PMD...
Solid low-bend-loss transmission fibers using resonant suppression of higher-order modes
transmission fibers resonant suppression higher-order modes
2015/7/30
Ring-assisted fibers suppress unwanted modes, improving the tradeoff that limits bend loss. Fabricated fibers achieve low bend loss and compatibility with standard fibers required for fiber to the hom...
