✦ Synopsis

Using modified chemical vapor deposition and solution doping techniques, Ž . erbium-doped fibers EDFs were prepared based on cesium᎐silicate glasses.

Ž . The possibility of manufacturing high-concentration 1᎐13 wt% EDFs was shown, and a fiber structure was realized by means of direct doping of cesium᎐silicate glass with erbium ions. The optical, fluorescence, and gain properties of prepared samples were examined. A maximum gain of 25 dB at 1538 nm was achieved in the fiber at an optimum length of 30 cm at a pump power of 50 mW at 979 nm.

A new all fiber temperature sensor is proposed and demonstrated based on a pair of 1 meter erbium-doped fiber (EDF), which are respectively macro-bent and straight. The sensor has a linear normalized loss (dB) response to temperature at 6.5 mm bending radius and 1580 nm input wavelength. The main ad

In this paper, a multiwavelength erbium-doped fiber laser based on a microstructure fiber Bragg grating (FBG) is proposed and demonstrated. The fiber Bragg grating is fabricated in a large-air-hole microstructure optical fiber using the phase-mask method. The laser based on this novel grating can be

## Abstract A novel reflection L‐band erbium‐doped fiber amplifier, based on a fiber loop mirror, is constructed. This amplifier reflects the backward ASE to the EDF as a secondary pumping source. A gain of 30 dB (an increase of 6 dB) is obtained, compared to the forward‐end‐pumped EDFA in the rang

## Abstract We present a single‐pass L‐band erbium doped fiber amplifier (EDFA) based on a large mode area (LMA) fiber. A single transverse mode is maintained through restricted mode launch. Pump light near 974 nm is sent into the core and has high spatial overlap with the signal beam, helping to p

## Abstract An actively mode‐locked fiber laser (AMLFL) based on the hybrid gain of a dispersion‐shifted fiber (as the Raman gain medium) and an Erbium‐doped fiber (EDF) is introduced. The fiber Raman gain mechanism can effectively suppress the gain competition of an EDF, which usually results into
