| Popis: | In wireline optical networks, planar lightwave circuits are next generation components capable of performing enhanced optical functions. Ultraviolet (UV) photoinduced refractive index increase at 193 nm was obtained experimentally in hydrogen-loaded doped silica glasses (P2O5 ∼ 1.5 mol% and B2O3 ∼ 9 mol% codoped, and phosphorus-doped P2O5 ∼ 8 mol%) used to realize channel waveguides. Refractive index variations (up to 9 × 10−3) were measured using the prism-coupling technique and a two-component model is proposed to interpolate the experimental data of Δn against total UV exposure fluence (kJ/cm2). |
