KALLISTOS

A design optimization tool for photonic devices

Create optimal S-Bends

with Kallistos and FIMMPROP

 

We gave this to Kallistos...


and got back this!


Taper before optimization Taper after optimization

 

The device on the left shows two waveguides joined by a linear section. The losses are considerable, the power transmission into the output fundamental mode being only 35%. KALLISTOS was configured to seek a design with the same length, but with improved transmission. The result was the "s-bend" on the right. Note how the optimizer automatically chose to include offsets at the waveguide interfaces!
