What is believed to be the first planar optical waveguide was formed in BiB3O6 (BIBO) crystal by 2.8-MeV He+-ion implantation with a dose of 2×1016ions/cm 2 and 2.8-MeV P+-ion implantation with a dose of 1×1014ions/cm 2 at room temperature. We observed 21 darks modes for the He+-ion-implanted BIBO waveguides and four dark modes for the P+-ion-implanted waveguides. The refractive-index profile of the He+-implanted BIBO waveguide was analyzed. The data also suggest that the BIBO waveguides formed by MeV He+-ion and P+-ion implantation differ in their developing mechanisms.
