An optical sensor based on dual asymmetric Mach–Zehnder interferometers (AMZIs) cascade with temperature-independent is proposed. The optical sensor based on AMZI is very sensitive to the change of ambient temperature. The temperature shift will lead to the change of the refractive index of the opti...
