Five Orders of Cascaded Raman Fibre Laser Oscillation From 1550 nm to Mid‐IR at 2334 nm Wavelength
Electronics Letters, Volume 61, Issue 1, January/December 2025.We experimentally demonstrate five orders of cascaded Raman oscillations (Raman lasers) in a fibre, starting from ∼1550 nm until 2334 nm. ABSTRACT We demonstrate a cascaded Raman fibre laser (RFL) oscillation up to the fifth order Stokes wave, from ∼1550 nm to mid‐IR at 2334 nm, with silica fibres.

IET Optoelectronics, Volume 18, Issue 6, Page 179-187, December 2024.Multicore (MC‐) erbium‐doped fibre amplifier (EDFA) architecture is classified from the viewpoint of the number of erbium‐doped fibre (EDF) cores and its pumping method. In particular, the advantages of cladding pumped MC‐EDFA are shown. Abstract Amplification technologies needed for spatial division multiplexing (SDM) signal transmission have been ...
