Optimisation of Optical S-Bend Waveguides

Simulation with Kallistos and FIMMPROP software


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!
