Demonstration of continuous multiple access with image-rejection coherent receiver and DML transmitters
Autor: Tabares Giraldo, Jeison, Masanas Jiménez, Miquel, Cano Valadéz, Iván Nicolás, Prat Gomà, Josep Joan
We demonstrate a UD-WDM PON using DML transmitters with multilevel intensity modulation, both in base-band and RF, and a spectrally-efficient heterodyne receiver. We provide comparison with a homodyne receiver. Two users at the same IF are detected s
