Abstract :
Summary form only given. Recently, chalcogenide glasses have generated much interest because of Kerr nonlinearities, which can be up to 600 times higher than in silica glass at the 1.55-/spl mu/m communication wavelength. Possible applications include low peak power, ultrafast all-optical switching using waveguide lengths of only a few centimeters embedded in a photonic circuit. Bragg gratings take an important place among the useful integrated components. They can be used as wavelength selective elements in wavelength-division multiplexing (WDM) networks or as dispersion-compensating elements. We present novel technique for fabricating strong Bragg gratings in chalcogenide glass waveguides.
