AB  - In this paper, a miniature Fabry-Perot temperature probe was designed by using 
      polydimethylsiloxane (PDMS) to encapsulate a microfiber in one cut of hollow core 
      fiber (HCF). The microfiber tip and a common single mode fiber (SMF) end were 
      used as the two reflectors of the Fabry-Perot interferometer. The temperature 
      sensing performance was experimentally demonstrated with a sensitivity of 11.86 
      nm/ degrees C and an excellent linear fitting in the range of 43-50  degrees C. This high 
      sensitivity depends on the large thermal-expansion coefficient of PDMS. This 
      temperature sensor can operate no higher than 200  degrees C limiting by the 
      physicochemical properties of PDMS. The low cost, fast fabrication process, 
      compact structure and outstanding resolution of less than 10(-4)  degrees C enable it 
      being as a promising candidate for exploring the temperature monitor or 
      controller with ultra-high sensitivity and precision.
