The optical property variation induced by temperature change for PbSe quantum dot (QD)-filled hollow core fiber was investigated as a function of particle size, waveguide length, and doping concentration. The temperature coefficients of emission peak and intensity in QD-filled fiber were obviously size-dependent. The fiber filled with 4.5 nm PbSe QDs had better temperature stability in emission wavelength. The mechanism of the output loss in fiber was established, based on the thermal quenching of QD luminescence and the guided mode leakage arising from the temperature dependent refractive indexes of the fiber core and the cladding.
