Antibunching, a key characteristic of single-photon sources, is crucial for quantum cryptography and quantum computing. Nonlinear couplers have significant potential as generators of nonclassical light. However, Limited research has been reported on antibunching in nonlinear couplers. This study investigates antibunching in an innovative design of a nonlinear coupler featuring three nonlinear waveguides, each comprising a material that exhibits the second-order nonlinearity.
