Abstract:
Optical switches include a first hybrid coupler configured to accept an input and to provide two branches. A phase tuner on a first branch includes a phase shifter. A first heater is positioned on the first branch and a second heater is positioned on the second branch, each configured to compensate for phase error. A second hybrid coupler configured to recombine the two branches. A first photodetector and a second photodetector are positioned at outputs of the second hybrid coupler and are configured to measure crosstalk between the outputs of the second hybrid coupler. A controller is configured to activate the first heater or the second heater to reduce the measured crosstalk.

Claim (Index 17):
The system of  claim 16 , wherein the controller is further configured to activate whichever of the first heater and the second heater is not already activated if the activation of the already activated heater failed to reduce crosstalk.
