چکیده انگلیسی
The linear and nonlinear response of Fabry-Perot etalons containing a polymer microcrystal solution was studied using the pump-probe technique with a white-light continuum probe. The response was studied at wavelengths away from resonance (700-800Â nm) when a near-resonant subpicosecond pump pulse (at 640Â nm) was used. A theoretical model used to describe the F-P linear transmission is presented. A blue-shift of the F-P peaks induced by the pump-pulse was clearly observed in all the etalons studied, and the magnitude of the shifts is used to quantify the nonlinear response. The potential of these devices for all-optical switching applications is assessed through the figures of merit W and T, and the recovery time of the nonlinearity. Refractive index changes as large as 1.2Â ÃÂ 10â2 were measured and switching energies as low as 0.9Â pJ were calculated at the F-P peaks. The nonlinear response was shown to have an ultrafast recovery, of around 2Â ps.
