- Abstract
- A simple structure of low-loss large-angle abrupt-bend waveguide is proposed. The normalized transmitted powers of the proposed structure are as large as 0.99 and 0.92 for bend angles of 5째 and 7째, respectively. Experimental results of silica-based planar lightwave circuit-type 5째-angled bends agree well with beam propagation method simulations.
