摘要:
Ultra-narrow linewidth, nonpolarizing guide-mode resonance (GMR) filters with single and double common resonance wavelengths are designed.The guide-mode resonance filters consist of a single grating layer with asymmetric profiles.By choosing appropriate parameters, same resonance wavelengths for both transverse electric (TE) and transverse magnetic (TM) polarizations can be achieved.Results show that high reflection (more than 99.9%) is obtained at every resonance wavelength, and the full-width at half-maximums (FWHMs) of TE- and TM-polarized light are only 0.008 and 0.215 nm, respectively.
