Abstract :
A carrier-injection-type semiconductor optical switch for photonic switching in which a traveling-wave optical amplifier is integrated in the optical single-slip structure (S/sup 3/) switch to improve insertion loss and crosstalk is discussed. Preliminary experimental results are described. These results suggest that the carrier-injection-type optical S/sup 3/ switch with traveling-wave amplifier has the potential to realize a small-size but large-capacity optical switch array for photonic switching.<>
