Abstract
At the present time, phase-matched frequency doubling is the most efficient and compact method of producing green and blue light. Much progress has been made in the growth of bulk and periodic crystals1 for frequency doubling in cavities and also in the fabrication of periodic waveguides using inorganic crystals.- Poled polymers have received attention because they are easy to process using spin coating techniques, and thus makes them particularly suited for thin film waveguides.3'4 In this talk, we describe how free-standing poled films can be stacked to form bulk periodic "synthetic crystals" satisfying quasi-phase-matching conditions for second harmonic generation (SHG) and other parametric processes in through plane geometry.
