Abstract :
Fiber optic ring resonators constructed from a continuous strand of single-mode fiber and an evanescent wave directional coupler can show an asymmetric resonance characteristic due to coupler losses. The effects of this asymmetry on the conversion of laser phase noise into amplitude noise is discussed. A mathematical model, valid for highly coherent signals, is used to analyze even high-finesse ring resonators with a minimum of CPU time.<>
