TI - 10-Gb/s Wavelength and Pulse Format Conversion Using Four-Wave Mixing in a GaAs Waveguide JO - IEEE Photon. Technol. Lett. VL - 22 IS - 12 SP - 872 EP - 874 PY - 2010 DO - 10.1109/LPT.2010.2047009 AB - We demonstrate the simultaneous conversion of wavelength and nonreturn-to-zero to return-to-zero (RZ) format at 10 Gb/s, using four-wave mixing in a passive GaAs bulk-waveguide. A conversion efficiency of -28 dB (idler output relative to signal output) and a conversion bandwidth of 48 nm could be achieved in this waveguide, which was fabricated in a single photolithographic step. The conversion efficiency is also characterized and compared with simulated results. The converted RZ on-off keying (RZ-OOK) signal demonstrated a 1e-9 bit-error-rate receiver sensitivity penalty of 1 dB relative to baseline RZ-OOK. ER -
