In modern WDM/DWDM based optical networks, wavelength division is very important. Bragg gratings are used in many devices to reflect, and thus isolate, specific wavelengths of light. Chalcogenide glasses can be used to create such gratings due to photorefractive effects that take place when illuminated with near bandgap light. We have created holographic Bragg gratings in As2Se3 films by using a HeNe laser to illuminate the glass in a periodic interference pattern. Refractive index changes of 0.009 have been measured.
