Abstract:

The simultaneous patterning and stabilization of a polyurethane designed for its use in second harmonic generation has been achieved by photoinduced crosslinking of a poled film containing a titanocene photoinitiator. The crosslinked polymer shows good clarity and its NLO response remains stable for several weeks at 100 deg C. NLO, Non-linear optics, Photopatterning, Second harmonic generation.
