Abstract :
Summary form only given. In this paper, by infiltrating the microstructured holes of a PCF with a noble gas such as Krypton (Kr), which exhibits a drastic phase-change from gas to liquid at ultra-low temperatures as well as strong wavelength-dependent material dispersion characteristics, and by inscribing a BG of period into the PCF, we can succeed in utilizing a robust temperature sensor which can be effectively applied at ultra-low temperatures.
