Analysis of output optical power level in fiber-optic interferometric schemes with multiplexed sensitives elements

In this paper proposes a concept for independent calculation of parameters of elements in fiber-optic interferometric schemes with time-division multiplexing (TDM). The calculation method allows ensuring the equality of the optical power from all multiplexed sensitive elements, as well as evaluating the effect of deviation of the optical scheme parameters from the calculated ones. Using the example of two optical schemes, the implementation of this calculation concept, the sequence of obtaining mathematical expressions, and examples of calculation results are shown. The described calculation method can be directly used in the design of interferometric system with multiplexing of fiber-optic sensing elements.
