What is it about?

Bismuth-doped fiber amplifier is an attractive solution for expanding the information traffic of contemporary telecommunication networks. We have improved the characteristics of such amplifier in the means of output optical power and energy efficiency, while ensuring its telecommunication networks compatibility. Moreover, we conducted a novel fundamental research to study the impact of complex nonlinear effects in such amplifiers.

Why is it important?

There is a high demand on various digital services that require stable and broadband connection, i.e. cloud services, artificial intelligent solutions, online gaming, video streaming services and social media. Thus, the internet speed demand grows exponentially in the world every year. To tackle this demand, alternative optical bands can be used to transmit information. However, to use these exotic bands, novel optical amplifiers are required. Thus, here we expand our work on developing a telecommunication-compatible optical amplifier with improved energy efficiency and optical power.

Perspectives

We anticipate that use of the novel optical bands (know as multi-band transmission) will be a short-term to mid-term solution for expanding information capacity of telecommunciation networks.
