TEMPERATURE COMPENSATION METHOD OF AN OPTICAL WDM COMPONENT AND TEMPERATURE-COMPENSATED OPTICAL WDM COMPONENT

摘要

The invention relates to a temperature compensation method of an optical component using at least one cut-off or band-pass filter (2) and beam-guiding optics. The problem of the invention is to provide a method with which an optical component can be operated with a temperature-dependent band-pass filter (or cut-off filter) across a wide range of temperatures, and to provide a corresponding optical component that can be reliably operated across a wide range of temperatures. This problem is solved by the inventive method which is characterized in that the orientation of the beam (3) relative the cut-off or band-pass filter (2) is changed subject to the temperature of the component.
