We report here the characteristics of surface-normal optical filters based on Fano resonances on
patterned single crystalline silicon nanomembranes SiNMs , which were fabricated and transferred
onto transparent plastic substrates using a SiNM wet transfer process. Detailed experimental and
theoretical analyses were carried out on the angular- and polarization-dependent transmission
properties. The filter transmission is independent of the incident beam polarization under
surface-normal conditions. Angle-independent transmission was observed for specific Fano
resonances with certain polarizations. The measured angle-dependent transmission agrees well with
the simulated transmission and dispersion properties based on the propagation wave-vector
analysis. © 2008 American Institute of Physics.
