Ultra-wideband All-optical Interband Wavelength Conversion Using a Low-complexity Dispersion-engineered SOI Waveguide

We experimentally present a low-complexity dispersion-engineered all-optical wavelengthconverter using a photonic integrated-circuit based on SOI waveguide. We achieve a single-sided conversion bandwidth of ∼35 nm from C- to S-band, and successfully transmit a converted 1-channel 32-GBd single-polarization QPSK S-band data over a 100-km SSMF link.
