Third-order nonlinearities in organic semiconducting polymers via spatial self-phase modulation
Abstract The nonlinear refraction in two organic semiconducting polymers, namely MEH-PPV and PBDB-T, has been studied via spatial self-phase modulation (SSPM) using a 532 nm CW laser excitation. The results indicate that SSPM arises from both the optical Kerr and thermo-optical e...
