Nonlinearity Compensation for Coherent Optical Satellite Communications
Stella Civelli, Luca Potì, Enrico Forestieri +1
Optical satellite uplinks rely on high-power optical amplifiers (HPOAs) to overcome free-space attenuation and enable long-distance transmission. However, at high power levels, fib…

Coherent transceiver architecture enabling data transmission and optical identification
Stella Civelli, Marco Secondini, Pantea Nadimi Goki +1
We propose a coherent transceiver architecture able to transmit information and enhance the security of the optical network by identifying other optical systems and subsystems. Sim…
