Abstract :
Using deeply etched photonic wires on gallium arsenide, ultra-small bent waveguides with radii of curvature below 1 mum were fabricated. The maximum transmittance of a 90deg bend with radius of 2 mum can be enhanced to almost 99% at a wavelength of 1.55 mum, which corresponds to an attenuation factor of 0.05 dB per bend
