RT Journal Article T1 Purely absorptive bistability in double-ring cavities A1 Mejías Arias, Pedro Miguel A1 Martínez Herrero, María Rosario A1 Bernabeu Martínez, Eusebio AB A novel type of optical bistable configuration, namely the so-called double-ring (DR) device, is presented. The stationary solutions in the purely absorptive case for a homogeneously broadened atomic system are derived. In the mean-field limit it has been pointed out that use of a DR arrangement enables us to reduce both the length of the sample of the nonlinear medium and the response time of the device. Linear stability analyses have shown that the position and the length of the unstable regions of a given hysteresis cycle can be controlled, to a great extent, by means of the two new parameters of our DR scheme. Finally, it has been remarked that, in order to observe selfpulsing, the purely absorptive DR system. may present a similar behavior to that offered in the dispersive single-ring case.
