Proteins play an important role in organisms. The fast and high-accuracy detection of
proteins is demanded in various fields, such as healthcare, food safty, and biosecurity …

A novel (to the best of our knowledge) liquid level sensor based on multimode interference
(MMI) effects is proposed and demonstrated. By using a multimode fiber (MMF) without …

In this letter, we propose a compact hybrid fiber-optic sensor for seawater temperature and
salinity simultaneous measurements. The device consists of a hollow-core fiber (HCF) …

The proposed sensing device relies on the self-imaging effect that occurs in a pure silica
multimode fiber (coreless MMF) section of a single-mode–multimode–single-mode (SMS) …

An in-fiber optofluidic Michelson interferometer fabricated by femtosecond laser
micromachining technology was presented. The interferometer structure was prepared by a …

On-chip optical isolation plays a key role in optical communications and computing based
on silicon integrated photonic structures and has attracted great attentions for long years …

An interferometric sensor with a no-core fiber (NCF) spliced between single mode fibers
(SMF) and functionalized with chitosan (CS)/poly acrylic acid (PAA) self-assembled …

We demonstrated temperature-insensitive, label-free detection of SARS-CoV-2 spike protein
(SSP) by harnessing the complementary refractive index and temperature dependence of …

An optical fiber sensor for simultaneous measurement of liquid level and temperature is
proposed and experimentally demonstrated. The sensor is formed by the integration of a no …

The multimode interference (MMI) concept has been comprehensively studied in the past
few years in order to develop new optical devices [1]. Typically, the MMI-based fiber device …
