Pulse propagation in the presence of off-resonance local nonlinearities

Javier J. Sanchez-Mondragon, G. E. Torres-Cisneros

Frequency-dependent and nonlinear susceptibilities are common in nonlinear optics, but they are scarcely used in coherent resonant pulse propagation because of their complexity. Early studies1 include the frequency quadratic susceptibilities, but none was proportional to the spectral pulse strength other than in the time-dependent case.2 We consider the propagation of short duration pulses through a medium described by an ensemble of resonant two-level atoms embedded in a nonresonant but nonlinear host medium. The nonlinear susceptibility is given by monomial terms of the spectral pulse strength.

Nonlinear nonreciprocity and directional bistability in a ring resonator with a quadratic nonlinear medium

Armin Gasch, D. Jäger

The mutual interaction of counterpropagating waves in a ring resonator containing a medium with second-order dispersive nonlinearity is studied. The theoretical treatment of nonreciprocal propagation is based upon the novel coupling of counterpropagating and mode-locked first- and second-harmonic waves. The experimentally observed transfer characteristics of a high-frequency model system reveal a directionally asymmetric bistability. This nonreciprocity can also be attributed in the time domain to the occurrence of dissipative structures, i.e., to solitons traveling within the resonator.
