Abstract :
A subwavelength grating waveguide was numerically analyzed by a 3D finite element method. Waveguide parameters as core height, width, duty cycle, and index contrast were varied and its effects investigated. Frequency shifts of the order of 40THz were obtained for the dispersion relation.
