Summary:
We demonstrate cross-bar all-optical switching on an add-drop microring resonator on a chip made of periodical poled lithium niobate. Utilizing quantum Zeno blockade induced by sum frequency generation, a signal is switched between the resonator’s two output ports by a pump wave. The switching contrast is 3.35 and 8.27 dB, respectively, at the through and drop port during a quasi-continuous operation, and 5.15 and 9.01 dB during a pulsed operation. These results demonstrate a purely parametric approach to optical routing and computing for all-optical information processing.
