Abstract
A reconfigurable multiwavelength erbiumβdoped fiber laser, using two multimode fiber Bragg gratings (MFBGs), is presented. Two MFBGs in Lβband are cascaded to form two overlapping resonant cavities. Various configurations of fourβ, threeβ, or twoβwavelength lasing are demonstrated experimentally by appropriately controlling the two polarization controllers inside the cavities.

A short wavelength band erbium-doped fiber laser (S-band EDFL) is demonstrated utilizing a fiber Bragg grating (FBG) in unidirectional ring configuration. The amplification in S-band is achieved using an erbium-doped fiber with depressed cladding, which suppressed gains at longer wavelength. The las
A double-clad erbium/ytterbium-doped fiber laser (EYDFL) is demonstrated using a fiber Bragg grating (FBG) as wavelength selective filter in a linear cavity resonator. The effect of the FBG's wavelength on the performance of the EYDFL is also investigated. The slope efficiencies of the EYDFL are obt
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
We have realized and studied the fiber laser based on 4-core Yb-doped fiber and multimode Bragg grating as the input reflector. The lasing efficiency slope of 55% was measured. An investigation of the output emission has shown that the far-field pattern constitutes an interference picture. That allo
We have realized a set of multimode lasers based on a double-clad Yb-doped fiber and Bragg gratings written on a graded-index multimode fiber. Efficient laser operation in the spectral range of 1.03-1.09 ΞΌm has been observed. Spectral characteristics of the laser emission have been investigated.
