Paper Abstract

We demonstrate a new integrated narrow-band spectral filter which consists of a planar waveguide covered with a thin polymer film donated with molecules liable to persistent spectral hole-burning (SHB) at liquid helium temperature. We show that such a device performs as a miniature programmable narrow-band spectral filter with a transmission bandwidth less than 1 angstrom. In contrast to currently used techniques, the frequency resolution of a SHB filter is limited, in first place, by the width of the homogeneous zero-phonon lines of the chromophore molecules, and not by the geometrical dimensions of the device.
