16 x 10 Gb/s WDM bidirectional gating in a semiconductor optical amplifier for optical cross connects exploiting network connection symmetry

In order to further reduce the number of gating elements in space switches, the performance of 10 Gb/s wavelength division multiplexing (WDM) bidirectional semiconductor optical amplifier (SOA) gating is investigated, We demonstrate for the first time that a conventional SOA can be used for bidirectional WDM gating operation at 10 Gb/s by the use of holding light injection.
