R. Hui et al., ALL-OPTICAL PHASE MODULATION IN A TRAVELING-WAVE SEMICONDUCTOR-LASER AMPLIFIER, IEEE photonics technology letters, 6(7), 1994, pp. 808-810
A novel all-optical phase modulation and wavelength conversion has bee
n demonstrated in a traveling wave semiconductor laser amplifier. Even
though the optical gain modulation caused by the saturation effect in
a traveling wave semiconductor laser amplifier is sensitive to the si
gnal wavelength, the optically controlled phase modulation is relative
ly independent of the signal wavelength.
