(FR) DISPOSITIF PHOTONIQUE
Abstract
(EN)
A method of fabricating a photonic device is disclosed. The method comprises providing a photonic crystal layer (14; 14') having a principal surface (15; 15') and an array of optical scatterers (17), for example holes extending into the photonic crystal or pillars extending from the principal surface, and forming, over a region of the photonic crystal layer containing at least one optical scatterer, a layer (20) of material on the principle surface of the photonic crystal layer by inkjet printing.
