Scalable WDM phase regeneration in a single phase-sensitive amplifier through optical time lenses
We proposed a scalable wavelength-division multiplexing technique for phase regeneration using a set of optical time-lens-based Fourier processors combined with a single phase-sensitive amplifier. Using this technique, we demonstrate the highest reported number of regenerated wavelength-division multiplexed channels in a single regenerator.
This approach allows processing the WDM channels as a serial TDM signal without crosstalk in the nonlinear media used for regeneration and is highly scalable in WDM channels, enabling scaling from 4x WDM to now 8x and even 16x WDM regeneration. We believe this technique will generate great impacts due to its potential to increase transmission reach and data throughput in optical communication.
