Vj. Sanchezmorcillo et Gj. Devalcarcel, SWIFT-HOHENBERG-TYPE EQUATION FOR NASCENT 2-PHOTON OPTICAL BISTABILITY IN THE WEAKLY DISPERSIVE LIMIT, Quantum and semiclassical optics, 8(4), 1996, pp. 919-929
Two-photon optical bistability under the influence of transverse effec
ts is considered near the onset of bistability in the weakly dispersiv
e limit. A reduced-field equation of the Swift-Hohenberg type is then
obtained, showing the equivalence between two-photon and the usual one
-photon optical bistability in the considered limits.
