Long-period fiber gratings (LPFGs) were fabricated by self-annealing of a polymer-filled silica hollow optical fiber without an amplitude mask show high temperature sensitivity. The spectral characteristics are modeled using the transfer matrix metho

Photonic quasicrystals are unique structures having long-range order but no periodicity. It has been found that quasiperiodic structures give rise to unusual phenomena and properties that have not been observed in periodic structures. Recently, it ha

We report the bending sensitivity analysis of helicoildal long-period fiber gratings (H-LPG). Linear response of the resonant wavelength shift to the bending radius was achieved with a high sensitivity over 10 nm/m.
