The processing of photonic structures using layer-by-layer assembly of polyelectrolytes and in-situ inorganic nanoparticle synthesis is reported. This approach facilitates the precise tuning of layer thicknesses and therefore optical response, and conformal large area coverage. Refractive index contrast of the polyelectrolyte multilayers (see Figure) is enhanced and manipulated by controlling silver nanoparticle concentration and distribution.
