Abstract :
Er0.45Y1.55SiO5 crystalline waveguide burying Si-guide stripe was fabricated by radical-assisted sputtering (RAS). We evaluated the light propagation properties with pumping at 1.48m. The light propagation loss drastically decreases by 82 cm-1 in the RAS waveguide compared with the previous waveguide by sol-gel.
