Abstract

For detecting photo-induced refractive index changes directly in chalcogenide fibers, a heterodyne interferometer with a linear frequency modulated laser diode as light source is reported. Such technique can be employed in fabrications of both transmission and Bragg gratings in different kinds of fibers.
