We report a large group velocity dispersion of hybrid modes in a LiNbO3-on-insulator multimode rib waveguide. A peak dispersion of ±49000 ps/(nm.km) is obtained in the mode hybridization region between TE00 and TM10 modes with a full width at half m

Dispersion tailoring of asymmetric vertical-dual slot waveguides in Silicon-on-Insulator is performed. The asymmetry introduced in widths and position of dual slots are utilized to engineer the dispersion characteristics of the photonic waveguide.

Silicon slot waveguides are widely used for photonic sensing [1] and optical signal procesing [2]. We propose a novel slot formed when a sub-micron rib waveguide is slit with vertical symmetry resulting in L shaped rails to have Zero Birefringence (Z
