Abstract :
Electrical switching of fused vertical coupler (FVCs) is demonstrated. For a 3.5 mm long coupler, complete switching is observed at 3 V reverse bias. This low voltage is attributed to excess current induced internal heating and the thermo-optic effect. By changing the electrode design and reducing the excess current, a 6.9 mm long FVC with 12 V switching voltage is demonstrated
