Slot-line waveguide optical switch system and method

A method for controlling a slot-line optical switch system, the method comprising:

• providing an input optical signal to an input channel of a slot-line waveguide optical switch, the slot-line waveguide optical switch comprising a plurality of wall portions that are each formed from a high refractive-index material and that are arranged to form a channel portion comprising an electro-optic material interposed between the plurality of wall portions, the channel portion comprising the input channel and a plurality of output channels comprising poled electro-optic material;
• applying a voltage with a given polarity to an electrode coupled to a corresponding one of the plurality of wall portions to change a poling field direction in the plurality of output channels via the electro-optic material to switch the input optical signal to one of the plurality of output channels;
• and
• applying the voltage with a different polarity to the electrode to change the poling field direction in the plurality of output channels via the electro-optic material to switch the input optical signal to another of the plurality of output channels.
