The synthesis process and the waveguide fabrication conditions of melamine formaldehyde resin (MF) were investigated.We found that melamine formaldehyde resin forms optical transparent films and possesses optical transparency easily under certain conditions.The transmission losses of waveguides fabricated were about 0.50 dB·cm-1 at 632.8 nm.The nonlinear optical properties of the melamine formaldehyde resin doped with disperse red 1(DR1) were also studied.The Melamine formaldehyde resin showed good resolvability with nonlinear molecules.The optimum precuring temperature was about 100℃and the optimum poling temperature was about 140℃for Dr1 doped formaldehyde resin.The second order nonlinear coefficient d33 was about 39 pm·V-1 for samples doped with DR1 for weight ratio about 5%.The sample also showed good thermal stability.
The synthesis process and the waveguide fabrication conditions of melamine formaldehyde resin (MF) were investigated. We found that melamine formaldehyde resin forms optical transparent films and possesses optical transparency easily under certain conditions. The transmission losses of waveguides fabricated were about 0.50 dB · cm- 1 at 632.8 nm. The nonlinear optical properties of the melamine formaldehyde resin doped with disperse red 1 (DR1) were also studied. The Melamine formaldehyde resin showed good resolvability with nonlinear molecules. The optimum precuring temperature was about 100 ° C. and the optimum poling temperature was about 140 ° C for Dr1 doped formaldehyde resin. The second order nonlinear coefficient d33 was about 39 pm · V-1 for samples doped with DR1 for weight ratio about 5%. sample also showed good thermal stability.
