Optical Fiber Interferometers Based on Arc-Induced Long Period Gratings at INESC TEC
In this work, we review the most important achievements of an INESC TEC long-period-grating-based fiber optic Michelson and Mach–Zehnder configuration modal interferometer with coherence addressing and heterodyne interrogation as a sensing structure for measuring environmental refractive index and t...
