Monolithic-intergrated lenses and grating on Ag+-Na+ ion-exchanged planar waveguides

Fabrication and measurement of monolithic integrated waveguides with three parts, that is transmissive grating and two spheroidal geodesic lenses on Ag+ - Na+ ion exchanged glass substrate, is reported. The monolithic waveguides are measured using diode laser of 1.3 micrometers and the Bragg diffraction efficiency of grating of waveguides is 40%.
