Inhalt:
We propose an optical frequency shifter for dual-polarization signals using frequency conversion in fibre. We achieve THz-range frequency shift with the original signal suppression without an optical filter and demonstrate combining of two dual-polarization 400-Gb/s superchannels with acceptable in-band crosstalk.
