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 5/spl deg/ and 7/spl deg/, respectively. Experimental results of silica-based planar lightwave circuit-type 5/spl deg/-angled bends agree well with beam propagation method simulations.
