Fig. 1. (Color online) (a) Theoretical transmittance and reflectance spectra with various pitches of p=300 nm, p=400 nm and p=500 nm. As increasing pitches, the central wavelengths of the transmittance and reflectance are moving towards longer wavelength and the corresponding bandwidths are broaden as well. (b) Theoretical transmittance spectra for various birefringence at fixed values of central wavelength (λo=600 nm) and pitch (p=384 nm) whose spectral bandwidth is given by Δλ=pΔn.
