Abstract :
Pure optical phase modulation with a two-electrode semiconductor optical amplifier is demonstrated experimentally. The inherent amplitude modulation has been suppressed more than 50 times by modulating the two electrodes out of phase, whereas the overall phase response was reduced by only 7.5%. It has, furthermore, been found that the tolerances on the operating condition are not excessively stringent.
