WebA adiabatic taper used to connect a grating coupler and a single-mode waveguide is demonstrated with a taper length of 120 μm and a transmission of 98.3%. 2. THEORY In 1977, Milton and Burns proposed a simple design rule to ensure adiabatic operation in a symmetric Ti-diffused LiNbO3taper [9,10]. WebMode coupling in optical waveguide horns is described in detail. Analytic approximations for the coupling constant and phase difference are derived. For a parabolic-shaped horn an expression for the power transferred out of the lowest order mode is obtained, which demonstrates that long structures will be needed to maintain adiabatic operation. ci agent berm
