A Study on Refractive Index Changes Induced by Heating the Long-Period Fiber Gratings in Different Temperatures
Refractive Index Different Temperatures ong-Period Fiber Gratings
2015/5/15
A silica fiber and long-period gratings were heated to clarify the effect of the glass structure and the residual stress relaxations on the fiber index profile and resonance wavelengths.The profile ch...
Highly-Birefringent Tunable Long-Period Fiber Gratings in Hollow-Core Photonic Bandgap Fiber by Use of Mechanical Pressure
Gratings Fiber optics Photonic crystal fibers
2015/6/4
The mode coupling properties of highly-birefringent tuneable LPGs formed in HC-PBGF are presented. The mode coupling from the fundamental core mode to higher-order guided mode of a HC-PBGF is obtained...
Broadening Adjustable Range on Post-Fabrication Resonance Wavelength Trimming of Long-Period Fiber Gratings by Heating
Broadening Adjustable Range Post-Fabrication Resonance Wavelength Long-Period Fiber Gratings
2015/7/16
The adjustable range of resonance wavelengths of long-period gratings was broadened toward the blue side by heating, and the mechanism was studied. The large blue shift, 41 nm, was obtained by heating...
