Coupling properties of directional couplers based on special waveguides

Abstract: The coupling characteristics of a novel kind of directional couplers composed by two parallel non-conventional waveguides are theoretically analyzed in details. The coupling length as a function of the operating wavelength and their optical and geometrical parameters are determined by an efficient frequency domain finite element method.

“…The silicon-on-insulator MMIs are considered in Fig.2, the SWG unitary cell (Fig.2a) has width w = [5][6][7] μm along the y direction, grating pitch л = 190 nm, and the segment length l is our variable. For the Nanowires MMI in Fig We calculated the dispersion relation for the two first TE and TM modes of thetwo kinds of MMI waveguides for an interval of wavelengths.…”

“…A photonic crystal coupler and splitterwere also demonstrated in [3] analyzing the dispersion and propagation resulting in an ultra-broadband response, covering most of the bands used for optical communications. The use of planar waveguide dispersion engineering with subwavelength dielectric gratings opened new frontiers for designing new types of MMI couplers and other broadband integrated photonic devices [4] and [6][7][8][9][10][11].…”
