Abstract

For the butt-joint coupling between a single mode fiber (SMF) and a single mode dielectric slab waveguide (SMDSW) with a spherical fiber micro-lens (SFML), the influence of the aberration on the propagation characteristics and coupling efficiencies of the coupler are investigated by Monte Carlo simulation. Simulation results show that because of spherical aberration effects, the location of the waistof the focused beam is nearer to the geometrical focus than that of the aberration free fiber micro-lens (AFFML). And the coupling efficiencies less and the curves platter with respect to the AFFML..
