A Compact and Broadband 2×2 3-dB Adiabatic Coupler Based on Trapezoidal Subwavelength Gratings

We propose a compact, broadband 2×2 3-dB adiabatic coupler using trapezoidal subwavelength gratings on silicon-on-insulator platform. The proposed device is constructed by two tapered waveguides, which are composed of trapezoidal subwavelength gratings. Broadband 3-dB optical power splitt...
