Abstract
The nonlinear optical properties of luminescent conducting polymers from the poly(para-phenylene vinylene) (PPV) are investigated using femtosecond transient absorption (fs TA) and holography to address: the primary photoexcitations and their interacting behavior at high excitation densities; and the signatures of biexcitons and their ability to be harnessed for ultrafast holographic signal processing. The solutions and films of the PPV oligomer MEH-DSB, and several soluble PPV derivatives, are measured. The fs TA spectra of MEH-DBA show a positive band due to stimulated emission around 2.4 eV and a photoinduced absorption (PA) extending from 1.3-2.0 eV.
