A compound fiber ring resonator is made with a Fabry-Perot etalon buil
t inside a fiber ring that is fed through a 2 x 2 directional single-m
ode fiber coupler. It is theoretically analyzed by an unfolded equival
ent model and a transfer-matrix method. The output intensities are pre
sented, and four cases are discussed. The results may be useful in app
lications such as fiber spectrum analyzers, sensors, and lasers.
