Mid-infrared refractive index sensor with high sensitivity and wide detection range based on multimode interference in tellurite optical fibers
In this paper, a section of tellurite no-core optical fiber (NCF) is compactly sandwiched between two segments of tellurite single-mode optical fibers (SMF) to form multimode interference (MMI) sensor for refractive index (RI) measurement. Theoretical investigation reveals that the sensitivity of th...
