Optical microfibers (MF), as a connection between fiber optics and nanotechnology, can realize enhanced light-matter/environment interactions, which benefit for optical sensing applications. In this paper, we introduce the fundamental working mechanisms of MF-based sensors review their recent progress status. We also discuss challenges opportunities MF provide some clues future work.
The achievement of functional nanomodules for subcellular label-free measurement has long been pursued in order to fully understand cellular functions. Here, a compact nanosensor based on fiber taper and zinc oxide nanogratings is designed applied the early monitoring apoptosis individual living cells.

Gas sensors have broad applications for either industrial process control or biological detection. We developed a versatile and compact optical hybrid coupler gas sensor composed of polymethyl methacrylate microwire silica microfiber. The light propagating in the microfiber interacts with polymer microwire. When is exposed to different concentrations ethanol vapor, refractive indices surroundings are changed, resulting shifts resonant wavelength. experimental sensitivity vapor 0.65 pm/ppm.
Abstract Graphene's atomic thickness, gapless Dirac–Fermionic band structure, and large thermal conductivity make it a promising element for applications in photonic integrated devices. Importantly, actively tunable graphene‐waveguide‐integrated optoelectronic devices can potentially be utilized the realization of reconfigurable systems. Since electrical device control is always preferred, researchers have previously demonstrated gate‐variable graphene devices; however, remains challenging,...
Efficient second harmonic generation (SHG) employing quasi-phase-matching (QPM) method based on the spatial modulation of mode intensity has been demonstrated experimentally and theoretically in optical fiber coupler system for first time.
