Abstract :
The first planar optical waveguide was formed in neodymium sodium yttrium tungstate (Nd:NaY(WO4)2) crystal by 2.6 MeV He+ ion implantation at a dose of 1.5×1016 ions/cm2 at room temperature. The dark modes were measured using the prism-coupling method. The refractive index profiles were analyzed using the reflectivity calculation method (RCM). TRIM’98 (transport of ions in matter) code was used to simulate the damage profile in Nd:NaY(WO4)2 by 2.6 MeV He+ ion implantation. The fluorescence spectrum of the sample was measured.
