Abstract
An optical attenuator and process for manufacturing optical attenuators. The optical attenuator includes an optical fiber installed in a tube so as not to be influenced by a change in external circumstances, and at least one grating formed in the optical fiber, for breaking total reflection conditions by varying refractive indices of a core layer and a clad layer of the optical fiber in order to attenuate incident light during optical transmission.
