Left) layout and operating principle of the single resonance filter obtained
by spectral sinusoidal sampling [39], [40]. (Right) Experimental versus
theoretical results for uniform and Gaussian apodization of the broadband
source. (a) Shaped spectrum of the optical source (uniform and Gaussian).
(b) Measured responses for the MWP filters using a uniform and Gaussian
shaped input source. (c) Theoretical response for the MWP filter using a
Gaussian-shaped input source.
