All-Optical Poling Properties of the Host-Guest Adulterant Thin-Films


Article Preview

The poling conditions were studied in AOP process by second harmonic generation (SHG) for host-guest adulterant thin-films. The guest was 4’-Nitro-4-dimethylaminoazobenzene and host was PMMA. The experimental results showed that the optimal poling temperature was about room temperature, the optimal ratio of light intensity of fundamental signal (ω) and its second harmonic signal (2ω) during AOP was approximately 100, the thin films had the same rule that the saturated value of SHG depended on the ratio. In addition, we obtained a suitable thickness around 2200nm that the stronger SHG after poling was generated.
