Abstract :
The coupling characteristics of a silica based waveguide type directional coupler with asymmetrical structure are studied by the beam propagation method. The coupling behavior of optical power from a single mode 3 mm guide into a multi-mode guide in silica are clearly demonstrated. The coupling into a second guide of <27 μm causes only a small loss, but the coupling into a 54 μm guide involves a significant loss
