Abstract

Bending losses lower than 0.7 dB for 90° bend sections with radii of curvature as small as 75μm were measured on silicon-based Al₂O₃ ridge waveguides with SiO₂ cladding layers at a wavelength of 632.8 nm. These values, which are close to the calculated values, are the lowest thus far reported.
