Abstract

Glasses doped with Cd S_l-x Se_x semiconductors form an important class of nonlinear materials in that they exhibit large third order nonlinearity with fast relaxation times, making them attractive for signal processing applications¹. Nonlinear prism coupling in a sputtered glass waveguide in color glass substrates with a cw threshold of the order of 200mW has been reported². K⁺-Na⁺ ion-exchanged waveguides in sodium rich Cd S_l-xSe_x doped glass have been fabricated³, and thermal nonlinear prism coupling under pulsed regime has been reported in ion-exchanged as well as sputtered glass waveguides [4,5].
