Mfc. Stephens et al., Wavelength conversion at 40Gbit/s via four wave mixing in semiconductor optical amplifier with integrated pump laser, ELECTR LETT, 35(5), 1999, pp. 420-421
A pump laser is integrated with a semiconductor optical amplifier to provid
e a compact, stable wavelength conversion device employing non-degenerate f
our wave mixing. A 40Gbit/s signal has been successfully wavelength convert
ed for the first time in such a device.
