Abstract
Glasses doped with Cd Sl-x Sex 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 Sl-xSex 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].
