In this paper, we propose a fiber-based two-wavelength heterodyne interferometer as a compact and highly sensitive displacement sensor that can be used in inertial sensing applications.
In this paper, an in-line Mach-Zehnder interferometer embedded in a fiber Bragg grating (FBG) is fabricated by a tiny offset-core splicing technique and inserted into a fiber ring laser to effectively
This work presents a compact hybrid fiber-optic sensor that integrates the packaged ring-shape MFI with the TFBG to realize wavelength–intensity dual demodulation for simultaneous pressure and
We report a dual-wavelength fiber laser sensor based on a uniform fiber Bragg grating (UFBG) and a Polyvinyl alcohol (PVA) film-coated long-period grating (LPG) as sensor probe for
With this new fabrication technique, it is possible to desing optical fiber reflectors, with a tailored wavelength response, to achieve a flat and stable wavelength emission.
This work presents a dual-wavelength C-band erbium-doped fiber laser assisted by an artificial backscatter reflector. This fiber-based reflector, inscribed by femtosecond laser direct writing, was
In this paper, an in-line Mach-Zehnder interferometer embedded in a fiber Bragg grating (FBG) is fabricated by a tiny offset-core splicing technique and inserted
Imagine a world where the Internet doesn''t just connect but senses—detecting earthquakes, monitoring battery health, or safeguarding
Imagine a world where the Internet doesn''t just connect but senses—detecting earthquakes, monitoring battery health, or safeguarding critical infrastructure. This is the power of

This study aims to propose an efficient design for a distributed polymer optical fiber system. This system combines traditional intensity-based measurement with wavelength-based
This study proposes the development of a dual-wavelength optical fiber sensor (DWOFS) that integrates two optical fiber structures in a multimode transmission line to measure the
Here, we demonstrate simultaneous frequency locking of two wavelengths of the multi-channel hybrid-integrated laser source to the resonance frequencies of a high Q-factor SiN
