Abstract

"This paper proposes a technique to accomplish optical multiplexing through FWM interaction. It is theoretically argued how two OOK WDM channels may be multiplexed into a single optical ASK-4 channel. Simulation results corroborate theoretical expectations. It is also presented an analysis for optimal level detection and simulations for optical ASK-4 transmission through different kinds of fiber. The technique presented is in accordance to some recent attempts to increase spectral efficiency and is appropriated for operating in modern all-optical networks."
