Optimization of a polarized light detector for a polarizing optical fiber sensor

conference paper

English

This paper analyzes the method of measuring optical power with an emphasis on the known methods of measuring the power of polarized light propagating through an optical fiber by two polarization axes. The method relies on monitoring the change in the behavior of the sensor fiber parameters when the temperature conditions in its surroundings change. This work deals with the possibilities of measuring the optical power for each propagation axis separately. Simultaneous measurement of the instantaneous state of polarization and a very accurate measurement of the wavelength makes it possible to obtain the necessary information about nonlinear phenomena in the optical fiber. The design of various connections that were selected for implementation in the laboratory is described in detail. The practical implementation includes a set of measurements under different conditions in which a source of temperature change was applied and the response of the parameters to these changes was monitored. The results were measured with a polarimeter and a power meter and are presented in graphs and summarized in the discussion.
