Abstract

One‐photon and two‐photon optical properties of a novel nonlinear chromophore 4,4′‐bis(triphenylamino‐trans‐styryl)‐biphenyl (BTSBP) doped polymethylmethacryate (PMMA) are presented. Two‐photon absorption (TPA) cross section (δ) of BTSBP was determined through the two‐photon‐induced fluorescence method by using Rhodamine B as a standard at the excitation wavelength of 800 nm pumped with a Ti:sapphire femtosecond laser. A three‐dimensional (3D) photonic crystal with a period of 4 µm was fabricated indicating BTSBP is an efficient photoinitiator for two‐photon microfabrication. (© 2005 WILEY‐VCH Verlag GmbH & Co.
