Fiber laser sensors have been present for almost four decades as versatile sensing devices
with a simple demodulation process, high sensitivity, and competitive resolution. This work …

Laser gyroscopes<? TeX 2pc 0pt?> afford extremely precise measurement of ultraslow
angular velocity and play an irrefutable role in engineering seismology, tidal detection …

We demonstrate a bidirectional mode-locked erbium-doped fiber laser by incorporating gold
nanofilm as a saturable absorber (SA). The gold nanofilm SA has the advantages of high …

We report a passive mode-locked fiber laser that can realize single-wavelength tuning and
multi-wavelength spacing tuning simultaneously. The tuning range is from 1528 nm–1560 …

We study the amplification of a weak magnetic field with the weak-value amplification (WVA)
technique based on the Faraday magneto-optic effect. By using a different scheme to …

Almost all inertial navigation systems rely on optical gyroscopes, operating on the Sagnac
effect. Laser gyroscopes demonstrate high precision in demanding applications such as …

In this article, the design and simulation of an optical gyroscope based on a hybrid ring
resonator using the Sagnac effect are presented. In this design, by using a transfer matrix …

Interferometric fiber optic gyroscopes are widely used in spacecraft, navigation, and
autopilot and missile systems due to their high accuracy and fast speed. However, the …

In sensors, the highest precision in measurements is given by vacuum fluctuations of
quantum mechanics, resulting in a shot noise limit. In a Mach–Zenhder interferometer (MZI) …

In this paper, we propose a scheme for angular rotation Ω measurement in an optic-fiber-
based Sagnac interferometer based on cascaded weak-value amplification (CWVA). CWVA …
