Effect of UV Uniform Exposure on Coupling Characteristics of Long-Period Fibre Gratings
UV uniform exposure can effectively vary the coupling characteristics of the annealed long-period gratings (LPGs) in hydrogen-loaded fiber. With the increase of UV exposure, the resonance wavelength shifts toward longer wavelength and resonance peak intensity increases first and then decreases. A theoretical explanation for this phenomenon has been given.
