a, The simulation of mode field distributions in the fiber cross section (excited by a TFBG) for light-to-heat measurements and approximate radial temperature distribution. b and c, Mode power distributions near the fiber surface and within the 8.2 m diameter fiber core. d, Thermal sensitivity of the HC (99) mode and of the core mode to ambient temperature changes. e, Temperature increases at the fiber surface determined from the wavelength shift of the HC (99), LC (49) and core mode with 1 min of CW laser irradiation, according to the sensitivity obtained from d, and simultaneous observation of no wavelength shift of the core mode resonance. Error bars result from the standard deviation from five measurements.
