AB We demonstrate theoretically and experimentally that a wide-range tuning of group delay values can be achieved in alossy fiber ring resonator. The tuning mechanism relies simply on varying the loss/coupling ratio in the resonator. Thissimple structure may be used advantageously in different regimes for many sensing configurations, both for achievingextremely high sensitivity enhancements (by working close to critical coupling, where the group index becomesextremely large) or suppression of undesired refractive index effects (e.g. Kerr effect), by working in the under-coupledregime.
