Schematic of a two-dimensional microcolor filter matrix. The different colors represent the three different waveguide materials. The functions nλ1(x), nλ2(x) and nλ3(x) describe the refractive index distributions for the different wavelengths λ1, λ2, λ3. The parameters d1, d2, d3 specify the widths of the waveguide channels A, B and C, respectively.
