A theoretical analysis of the temperature sensitivity of a multimode biconical fiber coupler as well as that of a multimode uniform fiber coupler has been given. The results show that a biconical coupler has some advantages over an ordinary fiber coupler as a temperature sensor or as a temperature-independent coupler.
