Abstract
This paper presents an innovative architecture where a micro-prism structure performs an in-line and wavelength-dependent extraction of the light injected at the edge of the device. This partial extraction of light is carried out by holographic mirrors coated onto each micro-prism oblique side. Thanks to the fabrication process, customization is possible and the number and the performances of each extractive faces can easily be tailored at will. These devices can be advantageous for any kind of applications where a high spectral selectivity is required or when a discrete extraction of spectral components has to be performed.
