The simplified seven cases of solvent swelling for a 1D bilayer stack. Changes of reflectance peak wavelength, λ_peak, and maximum reflectance, R_max, of a lamellar PhC structure corresponding to small variations of refractive index (±2%), and thickness (+5%). The initial lamellar PhC consists of 40 pairs with high ( = 1.60) and low ( = 1.45) indices and with the layer thickness equal to a quarter-wave optical thickness (). Depending on the refractive index of the solvent () and the preference of the solvent for each type of polymer layer, a wide range of responses can occur.
