A push-pull thermooptic interferometer switch can be controlled using only one control lead and one drive signal per switch. Advantageously, using only control signal lead and one electrical driver per switch can greatly reduce the complexity of the electronics needed to drive a switch array. The single control lead push-pull thermooptic interferometer switch can be driven by controllable voltage or current signals. The connections of the control and other signal leads to an array of these switched can be made in a planar manner without the need for crossover paths.
