This study will show that probing the oriental distribution of nonlinear optical (NLO) molecules during the poling process provides insight of the thermal stability of NLO response and the underlying interaction between the polymer and NLO molecules. Two types of aromatic polyimide films, poly(pyromelliticdianhydride)-DR 19 (PMDA-DR 19) and poly(pyromelliticdianhydride)-4,4'-diaminodiphenyl ether-DR 1 (POA-DR 1) were used. The second harmonic signal, temperature, and electric field were measured simultaneously during the poling.
