Summary:The filter (1) has a support layer (11) on which a set of reflecting elements (10) i.e. rectangular paving stones, defining a periodic network having parallel slots is formed. The support layer is made of a material having a refraction index, and includes inclusions (111) formed in a material having another refractive index lower than the former index. The inclusions level on a surface (112) of the support layer opposed to the reflecting elements. The inclusions are provided with specific height and width, and each inclusion is located partly between two reflecting elements. An independent claim is also included for a detector.
