In this paper one presents the results obtained in the development of a fiber optic temperature sensor based on the principle of the variation of the index of refraction of a liquid with temperature. The sensor is built by barincj the nucleus and replacinci the clad by the liquid which will act as a new clad with a hiqhly temperature dependent index of refraction. This intensity type sensor can work in several ranQes of temperature dependinQ on the particular I iquid used.

In a previous paper1 one described a sensor that worked by replacing a small region of the clad by a material possessing an index of refraction highly sensitive to temperature. The variation of the index of refraction of this material leads to tosses that modulate the transmitted optical power bringing information about the temperature.In this paper one presents a theory for the explanation of the behaviour of the above mentioned sensor.
