Abstract Reconfigurable waveguide components are promising building blocks for photonic neural networks and as an optical analogue to field-programmable gate arrays. By changing the effective index of waveguide, reconfigurable can achieve on-chip light routing modulation. In this paper, we design demonstrate Sb 2 S 3 -reconfigurable InP membrane Mach–Zehnder interferometer (MZI) on a silicon su...
