摘要：
Very high four-wave mixing (FWM) efficiency and signal-to-background ratio (SBR) are obtained in a 1.5-mm-long bulk semiconductor optical amplifier, The FWM efficiency is measured to be 5 dB at 1-THz pump-signal detuning, which is the highest value reported to date, With a pump power of -1.4 dBm, the SBR is in excess of 20 dB in a bandwidth of 12.5 GHz, for a pump-signal detuning range as large as 2 THz and the efficiency is under the same conditions larger than -1 dB for a pump-signal detuning range as large as 1 THz, These results make FWM an attractive method for practical wavelength conversion, Some low-detuning measurements show a maximum efficiency around 8 GHz.
