Titanium Dioxide Waveguides for Supercontinuum Generation and Optical Transmissions in the Near- and Mid-Infrared

We report the development of titanium dioxide-based waveguides for applications in the near- and mid- infrared. Thanks to embedded metal grating couplers, we demonstrate error free 10 Gbit/s optical transmissions at 1.55 and 2 μm. With additional management of the dispersion profile, we also demonstrate octave spanning supercontinuum in cm-long TiO2 waveguides.
