Description

technical field [0001] The invention relates to the fields of optical communication technology and nanometer material preparation, in particular to a PbSe quantum dot optical fiber amplifier in which ZnSe-doped sodium boroaluminosilicate glass is used as an optical fiber core substrate. Background technique [0002] Fiber amplifiers are an essential component of fiber optic communication lines, and with the advent of data waves and exponential growth in network traffic expected to continue indefinitely, bandwidth generation remains a challenge. One of the major limitations in implementing future high-capacity, ultra-broadband optical networks is the expansion of fiber bandwidth, which is beyond the capabilities of prior art signal amplification devices - erbium-doped fiber amplifiers, which are generally made of doped rare-earth ions (erbium , ytterbium, thulium-praseodymium or rubidium) optical fiber to generate gain to obtain optical signals, but these rare earth ions are ...
