Abstract

Recently, chaicogenide 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-µm communication wavelength.¹ 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.
