Abstract
All-optical poling at a significant spectral distance from resonance i s investigated in a new phosphine oxide ate-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-opt ical poling efficiency and resonant absorption of the non-linear polym er is considered in detail. Consequences for the device conversion eff iciency are discussed.
