Paper Abstract

In this paper, we design two tapered waveguides on the silicon-0n-insulator (SOI) wafers. The shape of designed SOI waveguides are linearly and exponentially taping varied along the propagation direction. The width of our designed SOI waveguide at starting point is 6 (mu) m, the end width is 20 (mu) m. We find out the optimal light launching position for maximum power output with single mode pattern. The linearly and exponentially tapered waveguides are compared. Finaly, we add a polymer layer as a cladding layer, the difference between the exponentially tapered waveguide and the linearly tapered waveguide with the polymer cladding are analyzed. The best deign of the tapered SOI waveguide with polymer cladding is obtained.
