Optical sensors based on asymmetric Mach–Zehnder interferometer (AMZI) are very sensitive to wavelength and temperature, and their shift will affect the accuracy of measured parameters. An optical sensor based on dual AMZIs, which is independent of both optical source wavelength and ambient temperat...
