We explore a type of synthetic saturable absorber based on quantum-inspired waveguide arrays or generally named as Jx array. We demonstrate the interplay of optical Kerr nonlinearity and Jx array can be used to observe saturable absorber phenomenon. More interestingly, we show that the boundary between on and off regime can be very sharp. The threshold optical intensity that marks this abrupt phase transition and its steepness can be engineered by varying the number of the guiding elements. The practical feasibility of these structures as well as their potential applications in laser systems and optical signal processing are also discussed.
