“…An all-optical poling, in which the aligning electric field is actually generated by the laser light has also been envisaged since 1993 on DR1M-MMA copolymer (Charra et al, 1993;Chalupczak et al, 1996) and subsequently applied to a new phosphine oxide azo-dye-MMA copolymer (Fiorini et al, 1997) achieving increased transparency with respect to the DR1 functionalized material, together with large secondorder properties. Differently from the polymeric DR1M-MMA material, efficient optical poling of thin films of norbornene functionalized with azo-dye have also been achieved, but without appreciable enhancement of second-order susceptibility, however, in the related polymeric poly-norbornene derivative, due probably to the increased rigidity of the polynorbornene backbone with respect to the poly-MMA backbone (Churikov et al, 2000). Accordingly, copolymers based on side-chain push-pull azobenzene grafted to poly(Nmethacryloyl-N'-phenylpiperazine) (3, Fig.…”

PACS 42.65. Ky, 78.66.Qn All-optical poling of side-chain azobenzene homopolymers PCN2 and PCN6, phenoxy] x-methylene methacrylate) for x = 2 and 6, with different spacer lengths was experimentally investigated. Due to the low absorption of the samples at 532 nm, it was found that there is a nearly quadratic increase in second-harmonic generation (SHG) when the film thickness of the sample films increases from 4 µm to 100 µm. The time constant τ A of the fitted photoinduced SHG decay process shows that PCN2 and PCN6 have higher temporal stability than the typical guest-host DR1-PMMA system, and different methylene conjugation lengths give slightly different time constants for disorientation. The possible reason from the molecule structure is discussed in detail.

In this paper, the fabrication and characterization of a high-index low loss polyethylene terephatate (PET) optical waveguide is presented. Dip-coating technique has been used to fabricate the optical waveguide using PET. Various waveguide properties, such as mode effective refractive index, optical loss, dispersion and waveguide thickness as a function of temperature of waveguides and substrates have been reported. Optical losses of as low as 0.7 dB cm )1 waveguides can be obtained if the formation temperature can be controlled between 30 and 35°C. In addition, we suggested that it is a suitable material for optoelectronic waveguide devices.
