Figure 3From: Tunable optical filters with wide wavelength range based on porous multilayersComparison of simulated shift of the central wavelength for low-doped and high-doped silicon photonic crystals. Comparison of simulated shift of the central wavelength due to tilting for high-doped (0.01 to 0.02 Ω cm) and low-doped (10 to 20 Ω cm) porous-silicon-based 1D photonic crystals.Back to article page
