Spectral resolution of optical filters based on diffractive optical elements with non-uniform illumination

H. Angelskår, A. S. Sudbø


We study the transmission coefficient and the spectral resolution of
optical filters based on a diffractive optical element (DOE), with a
collimating lens, input and output fibers. We limit our study to
filters that can be analyzed with a scalar (i.e., Fourier-optical)
formalism, and specify requirements that the filter geometry has to
satisfy for this formalism to give an accurate description. Finally,
we study the trade-off between power loss and spectral resolution in DOE-based filters.
