Phase modulation occurs when an external physical parameter—such as strain, temperature, pressure, or acoustic waves —interacts with the optical fiber. This interaction alters the effective optical path length that the light travels. Optical phase-modulation technique is a very powerful tool used in a wide variety of high performance photonic systems. Fiber-optic sensors and gyroscopes, integrated-optics sensors, or high-performance photonic integrated circuits are some examples of photonic systems where the optical. The phase change is converted into an intensity change using interferometric schemes (Mach-Zehnder, Michelson, Fabry-Perot or Sagnac forms). What would be the output intensities and fringe visibility from both outputs? The Michelson interferometer.
