Optical Fiber Based Mach-Zehnder Interferometer for APES Detection

Optical Fiber Based Mach-Zehnder Interferometer for APES Detection

A 3-aminopropyl-triethoxysilane (APES) fiber-optic sensor based on a Mach–Zehnder interferometer (MZI) was demonstrated. The MZI was constructed with a core-offset fusion single mode fiber (SMF) structure with a length of 3.0 cm. As APES gradually attaches to the MZI, the external environment of the...
