The theory of output intensities and field strengths of two variants of a four-port fiber-based device called a transversely coupled fiber Fabry-Perot interferometer is presented. The analysis is sufficiently general to consider both input and output from all four arms in both variants. Finesse is calculated for all modes of operation.
