The device on the left is an ultra short (7mm) linear taper giving about 53% power transmission into the output fundamental mode. KALLISTOS was configured to seek a design with the same length, but with improved transmission. The result was the oddly shaped device on the right, giving over 90% transmission! This was a large problem involving dozens of parameters controlling the taper shape. For more details see our contribution to LEOS 2003.
