Claim:
1. A method for applying a coating on a first end face of an optical component, the optical component having the first end face, a second end face, and two regions for guiding light, the two regions being a cladding and a core embedded in the cladding, the cladding forming a cladding front face on the first end face and the core forming a core front face on the first end face, the method comprising: covering the core front face with a mask; applying the coating onto the first end face; removing the coating and the mask from the core front face; and covering the core front face by applying a lacquer layer of a photo resist onto the first end face, exposing the photo resist to light from a rear side only in one of the cladding front face or the core front face, with light being input at the second end face of the component only in one of the two regions, and subsequently selectively removing the lacquer layer.
