Towards a Practical Implementation of Coherent WDM: Analytical, Numerical, and Experimental Studies

IEEE Photonics Journal, 2010
Future optical networks will require the implementation of very high capacity (and therefore spectral efficient) technologies. Multi-carrier systems, such as Orthogonal Frequency Division Multiplexing (OFDM) and Coherent WDM (CoWDM), are promising ...

All‐optical control of spatial beam intensity in multimode fibres by polarisation modulation

IET Optoelectronics, 2021
The authors demonstrate that by injecting a combination of LP11 modes in a few‐mode high‐birefringence fibres that all‐optical control of the spatial beam intensity at the fibre output is achieved by varying the polarisation at the fibre input.
