We report the fabrication and characterization of a hybrid silica photonic crystal fiber (PCF) with integrated chalcogenide glass layers and we show how the bandgaps of the fiber can be thermally tuned. The formation of the high index chalcogenide films on the inner surface of the PCF holes revealed resonances as strong as ~35 dB both in the visible and infrared regime. Temperature measurements indicate that the transmission windows can be tuned with a sensitivity as high as ~3.5 nm/°C. The proposed fiber has potential for all-fiber filtering and temperature sensing.
