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