Si-based 1D and 2D slot waveguides for magneto-optics

Although the new polymer based nano-composite materials that have been proposed for magneto-optic applications provide a high Verdet constant, they also exhibit high losses. These materials present a different challenge for realizing efficient integrated magneto-optic devices compared to traditionally used materials such as garnets. In this paper we study the figure of merit of 1D and 2D slot waveguide geometries and compare their advantages. In 2D slot waveguides the non-reciprocal TE/TM mode conversion, and in asymmetric 1D slot waveguides the non-reciprocal phase shift, respectively, are analyzed.
