Smart Fiber Laser System
Fiber lasers are divided into pulsed fiber lasers and continuous fiber lasers. LIFE mainly conducts research on the scenarios of femtosecond ultrafast fiber lasers and ultra-high power continuous fiber lasers. Femtosecond ultrafast fiber lasers mainly use fiber nonlinearity to achieve ultrashort and ultrastable pulses The ultra-high power continuous fiber laser mainly suppresses the nonlinearity of the fiber to achieve ultra-high power output. LIFE takes the lead in introducing intelligent control technology into the field of fiber laser, embedding intelligent algorithms into hardware platforms to realize real-time intelligent control, and achieving the above two main goals.

Intelligent Optical Fiber Communication System
In 2021, Huawei released the “Ten Mathematical Challenges for the Information Industry in the Post-Shannon Era”. Among them, the challenge involving optical fiber communication is“Optical Communication Nonlinear Channel Compensation Problem”, which is specifically broken down into fast and accurate modeling of optical fiber channels and Nonlinear Compensation Problem. Realizing low-complexity nonlinear accurate compensation through fast and accurate modeling of fiber channels, it is expected to approach the Shannon capacity limit of linear channels, break through the “capacity crisis”of fiber channels, and support the continuous growth demand of communication capacity. LIFE conducts continuous in-depth research on this key issue, introduces AI technology, and designs AI architecture and algorithms suitable for optical fiber communication systems, aiming to break through the key challenge of optical fiber nonlinear compensation.
