Abstract

Method for connecting an optical fiber to a GRIN lens, and a method for producing an optical filter module having an optical fiber and a GRIN lens, comprising arranging the optical fiber in contact with or in the immediate vicinity of the GRIN lens, directing a laser beam onto a part of the optical fiber and/or a part of the GRIN lens, the laser beam heating at least a part of the optical fiber and/or a part of the GRIN lens in such a way that a connection is formed between the optical fiber and the GRIN lens, and the optical axis of the laser beam being aligned oblique to the optical axis of the optical fiber, as well as optical filter modules produced in accordance with the method.
