Abstract

We report a new helicoidal long-period grating by twisting a photonic crystal fiber under CO₂ laser irradiation and experimentally investigated its novel transmission characteristics. The fabricated helicoidal PCF-LPG has a relatively short length of ∼1.4 cm with a low polarization dependent loss less than 1 dB and thermal shift of ∼3.7 pm/°C. The proposed device endows the unique resonant peaks tuning capability more than ∼18 nm by applying torsion stress, which has not been achieved in prior PCF-LPGs. From these novel thermo-optic and photo-mechanical properties, the proposed device can be applied for various components, including optical filters, attenuators, and sensors.
