摘要： In accordance with embodiments of the present invention, a nano-structured optical wavelength transmission filter (1) is provided. The optical filter (1) comprises a patterned substrate (10) on which a high refractive index dielectric waveguide (20) is arranged. A low index dielectric layer (30) is arranged on the high refractive index dielectric waveguide (20), on which an array (40) of metallic nanostructures (42a-42n) is arranged. The layers of the optical filter (1) have conformal shapes defined by patterned surface (10a) of the substrate (10).
The invention relates also an optical filter system (2) comprising the optical transmission filter (1) and a detector array (3) fixed to the substrate (10). The invention relates also to spectrometer (4) comprising at least one optical transmission filter (1) and/or at least one said optical transmission filter system (2), and has a spectral resolution of lower than 30nm for incident light having a wavelength between 300nm and 790nm.
The invention relates also to a method of fabrication of an optical filter (1), an optical filter system (2) and a spectrometer (4).
