Samenvatting

We present an electro-optical switch operating on TM polarized light in POLIS. All relevant electro-optical effects, including bandgap shrinkage, bandfilling, intra-band and inter-valence band absorption are modeled, properly accounting for the magnitude of these effects at various doping levels. Based on the results of the model switches were realized on POLIS material, and by optimizing the doping profile a decrease in switching voltage from 4.6 V to 2.8 V was obtained. A good agreement between the model and measurements was found. The switches have 3 mm long phase shifters and show low crosstalk values of -17 dB.
