Abstract

Phase-matched second harmonic generation over 7 mm is demonstrated using the modal dispersion of a composite 4-dimethylamino-4'-nitrostilbene/polyetherimde channel waveguide. For a l-mm-long sample a record figure of merit for polymers of eta=P-2 omega/(P(omega)L(2))=14%/W cm(2) was measured at 1550 nm. This is comparable to the value reported for LiNbO3 at that wavelength. The efficiency in longer samples is limited by fundamental and harmonic waveguide-losses.
