Abstract :
A novel structure called ridge coplanar waveguide is proposed for Mach-Zhender optical modulator. Numerical modeling using a two-dimensional finite-difference time-domain (2D-FDTD) algorithm has shown that a ridge coplanar waveguide on Y-cut LiNbO3 substrate without SiO2 buffer layer yields very high efficiency of modulation over a wide frequency bandwidth
