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.
