The generation of an octave spanning supercontinuum covering 488-978 nm (at -30  dB) is demonstrated for the first time on-chip. This result is achieved by dispersion engineering a 1-cm-long Si3N4 waveguide and pumping it with an 100-fs Ti:Sapphire laser emitting at 795 nm. This work offers a bright broadband source for biophotonic applications and(More)
We report on the development of low-loss photonic components fabricated in low-temperature PECVD SiN for the development of a CMOS compatible biophotonics platform. We discuss modeling and experimental demonstration of strip waveguides, MMI and evanescent couplers, fractal trees for power distribution and AWGs and waveguide-integrated resonators as(More)
