Abstract
An optical for wavelength reference measurement has in essence an optical conductor with integrated fiber Bragg grating that has a transmission maximum at a desired wavelength. Arranged downstream of the fiber Bragg grating is a photoreceiver receiving the measuring radiation beam passing through the fiber Bragg grating. If desired, it is possible to use a beam splitter to produce a reference radiation beam that is detected in a further photoreceiver.
