Page Content NEED Photonics integration on silicon for sensing, imaging and communication at near and mid infrared wavelengths. SOLUTIONCombination of two silicon-on-insulator (SOI) waveguide types with novel bends, waveguide conversion structures and switching methods. BENEFITS Ultra-dense integration of single-mode photonics on SOI chipsOperation over ultra-wide wavelength range (from 1.2 µm to >3 µm)Low propagation & coupling losses, small polarization dependency Tolerance to high optical powers PATENT PUBLICATIONS WO2003085430, WO2004023196, WO2006005787, WO2014060648 PUBLICATIONSHarjanne et al.
