Title

Efficient Second Harmonic Generation At 1.5 Μm In Composite Polymeric Channel Waveguides

Abstract

This paper demonstrates phase-matched SHG in a channel waveguide made of 4-dimethylamino-4'-nitrostilbene (DANS) side-chain polymer. The SHG figure of merit η= P$-2ω//(P$-ω/L)2 = 10%/W - cm2 is the highest non-resonant value reported for polymers and is comparable to those of inorganic crystals. Phase-matching between the TM00$+ω/ and TM10$+2ω/ modes is achieved using the modal dispersion of the waveguide. To optimize the overlap integral, the guiding region consists of a linear polyetherimide layer and a nonlinear DANS-layer. The two guiding layers are sandwiched between two buffer layers made of PC polymer. The samples were fabricated by multi-layer spin-coating, subsequently poled, and diced into pieces of different lengths for end-fire coupling. Finally, channel waveguides of various widths were fabricated by photo-bleaching through a mask.
