Abstract

Photonic space division (SD) switching systems are particularly promising and most practical for providing the necessary broad-band services for future telecommunication needs. A 32 line SD switching system employing polarization independent LiNbO₃ 8×8 switch matrices [1] has already been demonstrated for use in a Local-Area-Network [2]. Application expansion of such a switching system requires further increasing the line capacity to greater than 100 lines. Introducing semiconductor Traveling Wave Amplifiers (TWAs) to the switching network would be a very effective method for achieving such an increase [3]-[5].
