The application of reciprocity principles in optics has a long history that goes back to Stokes,
Lorentz, Helmholtz and others. Moreover, optical applications need to be seen in the context …

The unique combination of two gain media in Brillouin/erbium fiber lasers results in
distinctive properties of such sources. The paper describes in detail the output and efficiency …

In this paper, we present a novel Brillouin fiber-ring laser utilizing an unbalanced Mach-
Zehnder interferometer (UMZI) as coupling device. The laser is pumped by a distributed …

A novel long-tail optical fiber current sensor based on fiber loop ring-down spectroscopy
(FLRDS) and magnetic-tunable refractive index properties and magnetictunable …

We experimentally demonstrate a simple widely tunable multiwavelength Brillouin/Erbium
fiber laser that can be tuned over the entire C-band, thereby greatly improving the tuning …

A wideband multiwavelength Brillouin–erbium fiber laser (BEFL) with double Brillouin

A new fiber ring laser has been proposed which is composed of a laser diode amplifier, a
flint glass fiber as a sensing element, and a Faraday cell as a bias element, and applied to a …

The transmission light intensity method is carried out on a classical platform to study the
reciprocity of Faraday effect in water-based Fe3O4 ferrofluid and its diluents. Setting the …

We proposed and experimentally demonstrate a novel scheme of Brillouin/erbium fiber laser
(BEFL) in a ring cavity configuration. The Brillouin gain media, which is provided by a …
