Abstract

Polymethacrylate copolymers, containing non-linear optically active 4'-dialkylamino-4-nitro- azobenzene side groups and crosslinkable 2-butenyl side groups have been studied. Films of these copolymers can be thermally crosslinked at elevated temperatures and photochemically crosslinked by exposure with UV light; both methods allow the control of the crosslinking density. In situ second harmonic generation (SHG) of a Nd-YAG laser (1.064 micrometers ) while poling was used to study films with different degrees of pre-crosslinking. A pre-crosslinking step, prior to the corona poling step, can be applied to optimize alignment and relaxation of the chromophores. Depending on the conditions of pre-crosslinking, the SHG signal intensity and the alignment stability can be maximized.
