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 9):
The switch of  claim 1 , wherein the controller is further configured to activate the first heater or the second heater if the measured crosstalk at the first photodetector or the second photodetector exceeds a threshold.
