FREQUENCY-DOUBLING IN 2-COMPONENT SELF-ASSEMBLED CHROMOPHORIC WAVE-GUIDE STRUCTURES

Self-assembled chromophoric multilayers having large second-order opti cal nonlinearities can be combined with linear guiding materials such as polymethylmethacrylate to produce two-component frequency doubling waveguides, This approach introduces considerable flexibility in optim izing the trade-off between the overlap of waveguide mode profiles and linear absorption. Extremely low waveguide propagation losses can be achieved because electric field poling and the accompanying poling-ind uced optical scattering are obviated. (C) 1997 American Institute of P hysics.
