We propose a novel way to enhance the Sagnac effect by using a nonlinear ring interferometer. Specifically, we take advantage of the nonlinearly induced nonreciprocity of counterpropagating waves caused by the formation of an index grating in the nonlinear medium.

  5. As shown in Fig. 2, the enhancement factor η becomes less than 1 for some values of the pump intensity. This corresponds to a reduction of the Sagnac effect in the vicinity of the onset of symmetric bistability4(Δth=−3,Ath=8/93). ηmin and the minimizing pump intensity Amin are again given by Eqs. (9) and (10) but with the opposite signs before the radicals.
