First demonstration of WDM-enabled all-optical wavelength conversion with a SOA and a 2nd order micro-ring resonator ROADM

We present the RAWC, the first Ring Resonator Assisted Wavelength Converter employing a SOA and a tunable, Si<inf>3</inf>N<inf>4</inf>-SiO<inf>2</inf> micro-ring resonator ROADM. We demonstrate inverted, non-inverted and WDM-enabled wavelength conversion with low power penalties.
