Problems solved by technology

[0004] Since the existing rare earth luminescent glass has the disadvantage of a single and discontinuous luminescent band, in order to achieve full coverage of the near-infrared band, multiple devices are usually used to work together, which requires many devices and takes up a lot of space, which is not conducive to near-infrared devices. miniaturization

Description

technical field [0001] The invention relates to the technical field of near-infrared luminescent glass, in particular to a rare-earth-doped multilayer luminescent glass with full coverage in the near-infrared band and a preparation method thereof. Background technique [0002] Rare earth-doped glass is widely used in optical fiber amplifiers. At present, the main research is on rare earth-doped single-layer luminescent glass, but the luminescence band of single-layer luminescent glass is limited. The single-layer glass has a narrow and discontinuous light-emitting band, and this shortcoming of narrow coverage limits its application. [0003] The gain bandwidth of the fiber amplifier directly determines the number of channels. The larger the bandwidth, the more the number of channels, and the faster the energy and speed of information transmission. At present, the working window of most fiber amplifiers can only cover C-band (1530nm-1565nm) and L-band (1565nm-1625nm). With ...
