Abstract

A method and a device for coupling light to or from an optical waveguide, wherein a local resonance to a specific wavelength is provided in a portion of the waveguide intended for coupling the specific wavelength component of the light. Light coupling to or from the waveguide takes place at the portion with local resonance.
