5 September 2014 Supercontinuum generation in tapered rib waveguide
Author Affiliations +
We have designed a tapered rib waveguide and numerically studied the generation of supercontinuum using such waveguides. The Air-SF57 glass-SiO2 waveguide is 2 cm long, with a varying etched depth to manage the total dispersion. Numerical simulations are conducted for input pulses at a wavelength of 1550 nm. The proposed waveguide geometry greatly broadens the output spectrum extending from ~1000 nm to ~ 4600 nm at -30 dB level, caused by continuous modification of the phase matching condition for dispersive wave emission. The coherence property has also been investigated, demonstrating that fully coherent supercontinuum can be obtained with proper pumping conditions.
