Rastogi, N. Ashok, A. Kumar] We present a large-core planar optical waveguide design showing high group velocity dispersion (GVD). The design is based on a coupled asymmetric dual-core structure with an additional layer of over cladding. The resonance between the two dissimilar cores, namely, core-1 and core-2, has been utilized to achieve high GVD. The core separation controls the magnitude of the GVD. The resonance wavelength can be fine tuned by varying the parameters of the core-2. The over-cladding helps in maintaining high GVD even with large core-1. We show a GVD of 7.8×10−25s2/mm with the core-1 size as large as 6μm. Such a structure should find applications in the design of high-power integrated-optic dispersion compensators for optical telecommunication and ultrafast waveguide lasers.
