This paper presents a systematic review of the research available on salinity optic fiber
sensors (OFSs) for seawater based on the refractive index (RI) measurement principle for …

Alanine aminotransferase (ALT), a type of inactive enzyme largely present in fish liver cells,
is essential for the tricarboxylic acid (TCA) cycle. Monitoring ALT activity in the …

An ultrasensitive refractive index (RI) sensor based on enhanced Vernier effect is proposed,
which consists of two cascaded fiber core-offset pairs. One pair functions as a Mach …

Metasurface provides a novel way to modulate light energy at specific wavelengths, namely
resonances, where there is a sharp drop in the transmission spectrum. Based on the …

Micro-/nanofibers (MNFs) are optical fibers with diameters close to or below the wavelength
of the guided light. These tiny fibers can offer engineerable waveguiding properties …

Compact interferometers based on waveguiding structures have found countless
applications in refractive index measurements, chemical sensing, as well as temperature …

Optical fiber microresonators have attracted considerable interest for acoustic detection
because of their compact size and high optical quality. Here, we have proposed, designed …
