Abstract EN
The Mach-Zehnder interferometer (MZI) can be used to test changes in the refractive index of sucrose solutions at different concentrations.
However, the popularity of this measurement tool is limited by its substantial size and portability.
Therefore, the MZI was integrated with a small fiber-optic waveguide component to develop an interferometer with fiber-optic characteristics, specifically a fiber-optic Mach-Zehnder interferometer (FO-MZI).
Optical fiber must be processed to fabricate two optical coupling structures.
The two optical coupling structures are a duplicate of the beam splitter, an optical component of the interferometer.
Therefore, when the sensor length and the two optical coupling structures vary, the time or path for optical transmission in the sensor changes, thereby influencing the back-end interference signals.
The researchers successfully developed an asymmetrical FO-MZI with sensing abilities.
The spacing value between the troughs of the sensor length and interference signal exhibited an inverse relationship.
In addition, image analysis was employed to examine the size-matching relationship between various sensor lengths and the coupling and decoupling structure.
Furthermore, the spectral wavelength shift results measured using a refractive index sensor indicate that FO-MZIs with a sensor length of 38 mm exhibited excellent sensitivity, measuring 59.7 nm/RIU.
