Optical properties and reliability of recoated long-period fiber gratings for EDFA gain flattening

Joo-nyung Jang; Min-Sung Kim; Tae-Hyung Rhee; Kyung-ho Kwack

Coupling behavior of long-period fiber gratings (LPG) is very sensitive to ambient condition and bending. We used a UV-curable polymer with suitable refractive index and measured optical properties of recoated LPG. We applied it to filter design for EDFA gain flattening.
