Embodiment Construction

[0043] Examples are further detailed below.

[0044] A 19-core broadband high-gain fiber optic light source solution. It contains 19 cores made by MCVD, each core is doped with Bi 2 o 3 / Er 2 o 3 and other oxides ZrO 2 / SbO 2 / GeO 2 / Al 2 o 3 / La 2 o 3 one or more of them. The multimode pumps of 3 wavelengths (976nm, 830nm, 1480nm) are coupled into 19-core double-clad rare-earth-doped fiber through a double-clad fan-in beam combiner, and the spectra of multiple cores pass through a specially designed tapered fiber Mode conversion is performed and finally coupled out through a multimode fiber.

[0045] A 37-core broadband high-gain fiber optic light source solution. It contains 37 cores made by MCVD, each core is doped with Bi 2 o 3 / Er 2 o 3 and other oxides ZrO 2 / SbO 2 / GeO 2 / Al 2 o 3 / La 2 o 3 one or more of them. 7 multimode pumps with 3 wavelengths are coupled into 37-core double-clad rare-earth-doped fibers through a double-clad fan-in beam comb...

Abstract

The invention discloses an ultra-wideband high-gain multi-core optical fiber light source. A plurality of multimode pump lasers are adopted to generate a wide-spectrum spontaneous radiation spectrum in a plurality of doped multi-core double-clad optical fibers, then beam combination and tapering coupling are carried out, and finally, the whole high-brightness and ultra-wideband spectrum is outputthrough one optical fiber. Integrated parallel amplification is achieved through the multi-core multi-doped optical fiber, and finally the low-divergence optical fiber light source which is high in brightness, ultra-wide in band and flat in spectral line is obtained.

Description

[0001] (1) Technical field [0002] The invention relates to the field of optical fiber amplifiers for broadband communication transmission and broadband light sources for sensing applications. [0003] (2) Background technology [0004] The transmission capacity of optical fiber communication has been increasing continuously, and wavelength division multiplexing is one of the main ways to expand communication capacity. However, when applied to communication systems, due to the spectral characteristics of erbium-doped fibers, only C-band and part of L-band can be amplified. As a result, the main wavelengths of current communication systems only use C-band, L-band and 1310nm single wavelength. [0005] Optical fiber sensing has developed rapidly in recent years, and various sensors from grating to interferometric have played a huge role in the field of security and intelligent systems. However, optical fiber sensing is inseparable from light sources, especially the construction...
