%0 Journal Article %A Monzón Serrano, Juan José %A Sánchez Soto, Luis Lorenzo %T Amplitude response of a Fabry-Perot interferometer %D 2015 %@ 0143-0807 %U https://hdl.handle.net/20.500.14352/24136 %X The complex reflected and transmitted amplitudes from a Fabry-Perot interferometer are analysed using a phase-space approach, in which the real and imaginary parts of those amplitudes are taken as basic variables. As functions of the optical path length of the cavity, the reflected amplitude describes a circle, whereas the transmitted is given by a hippopede. The system performance can be directly related to the geometrical parameters of these curves. %~
