Abstract :
All-optical poling at a significant spectral distance from resonance is investigated in a new phosphine oxide azo-dye PMMA copolymer (PO-MA) showing increased transparency with respect to Disperse Red 1 (DR1), together with large second-order properties. Trade-off between all-optical poling efficiency and resonant absorption of the non-linear polymer is considered in detail. Consequences for the device conversion efficiency are discussed.
