Abstract

Vertical slots are used to reduce the nonlinearity of silicon-on-insulator waveguides. In properly designed slot waveguides, approximately 50% of the optical power can be confined in the air-slot and air-cladding region. Compared with a strip waveguide, a factor greater than 15 times more reduction in the real part of nonlinear coefficient can be achieved in the 100-nm wavelength range. In addition, vertical-slot waveguides exhibit large negative chromatic dispersion, which will induce phase mismatch and further suppress nonlinear parametric effects.
