Abstract

We propose a cascaded quasi-phase matched (QPM) lithium niobate (LN) device. In the device, two QPM-LN crystals with different domain inversion periods are cascaded. We numerically show that the cascaded QPM-LN device has an all-optical decision gate function, thus enabling a compact and stable 3R circuit.
