Switchable erbium-doped fiber laser using optical-injection controlling

Abstract

Abstract:In this paper, we propose and demonstrate a new wavelength-switchable fiber laser with all-optical controlling. By adjusting the power of injected light in a cascaded fiber Bragg grating overlapping cavity erbium-doped fiber laser, we obtained the switching among dual wavelength, single wavelength and zero wavelength. Meanwhile, the effect of optical injection in erbium-doped fiber laser was investigated, and the optimized wavelength to control the lasing wavelength has been found.Output power, dBm

“…A few wavelength-switchable fiber lasers have been proposed with various methods including using CW optical-injection controlling [1] , two polarization-maintaining fiber Bragg gratings(PMFBGs) [2,3] , a uniform PMFBG and a Sagnac loop mirror [4] , a multimode FBG [5] , cascaded PMFBGs in a Sagnac loop interferometer [6] , a nonlinear polarization rotation technique [7] , a nonlinear optical loop mirror incorporating multiple FBGs [8] , cascaded asymmetric exposure long-period fiber gratings [9] .…”

Wavelength switching based on quantum-dot vertical-cavity surface-emitting laser

“…Wavelength switching and tuning schemes are nec essary optical devices for optical communication sys tems and optical switching applications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Wave length switching schemes using quantum well semi conductor lasers have received considerable attention, owing to their compactness, simple of operation, low cost, and low power consumption [14][15][16][17][18].…”

A compact O-plus C-band switchable quad-wavelength fiber laser using arrayed waveguide grating

“…There are many methods of tuning or switching the output of a fiber laser. Notable methods include using fiber Bragg grating together with acousto-optic super lattice modulator [1], few mode FBGs [2,3], using AWG and broadband FBG [4], optical injection technique [5], using highly non-linear fiber and polarization controller [6][7][8], and using bismuth doped fiber [9]. Of late, there is also interest in dual wavelength output from a fiber laser for application in the areas of fiber optics sensors, optical spectroscopy and microwaves photonics systems.…”
