We demonstrate a liquid-crystal-filled photonic crystal fiber (PCF) and investigate its temperature response with a unique liquid crystal (LC) clearing point of 58 $^{\circ}{\rm C}$. Opposite temperature responses are observed at the temperature that is lower and higher than the LC's clearing point, respectively. Such a LC-filled PCF could be used to develop a promising optical switch with a broadband...
An optical fiber bend sensor assisted with a photonic crystal fiber(PCF) has been fabricated by splicing a section of photonic crystal fiber between two single mode fibers. Such a structure could be developed a Mach-Zehnder interferometer (MZI). The PCF-based MZI is sensitive to structure bending with a sensitivity of 6dB/m_1 and is independent on temperature only with a sensitivity of 0.01 dB/°C...
We reported a gas pressure sensor based on CO2-laser-induced long period fiber grating (LPFG) in an air-core photonic bandgap fiber (PBF). The LPFG was inscribed by use of an improved CO2 laser system with an ultra-precision two-dimensional scanning technique, which produced single side periodic collapses in the micro-structured cladding of the air-core PBF. Such LPFG was utilized to measure the gas...
