Abstract

Long period gratings (LPGs) can be made by rocking a single mode fiber and at the same time periodically scanning a focused CO2 beam across the fiber. A 15 period LPG with ∼ 3 degree rocking angle and 1.3 mm pitch exhibits a narrow bandwidth of 4.8 nm and a resonant attenuation of 33.5 dB. The novel LPG has a temperature sensitivity of -77 pm/°C and a strain sensitivity of -0.14 nm/ mε , and is insensitive to twist.
