Self-Defocusing and Optical Crosstalk in a Bistable Optical Etalon
Two transverse phenomena associated with a bistable optical etalon are discussed. The first is self-defocusing1 of the laser beam due to the nonlinear dispersion of the medium inside the bistable Fabry-Perot etalon. Good agreement is found between GaAs data and one-dimensional numerical simulations. The second is crosstalk2 between nearby bistable regions in the same etalon due to diffraction coupling, which is studied numerically in both one and two transverse dimensions.
