Abstract

A novel high-speed optical switch based on organic coumarin waveguide is presented. The device principle is based on influencing the bend loss in a waveguide by changing the refractive index contrast defining the guide. A low power femtosecond laser is used to excite the cladding of the curved waveguide. The beam propagation method is employed in the numerical simulation. The designed optical switch has a large extinction ratio and rapid response time (about 1.2ps).
