OPTIMIZED TAPER DESIGN:
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.
