ABSTRACT
A 2×2 optical switch structure was designed and investigated based on semiconductor optical amplifier cross-gain modulation technology. The 2×2 optical switch structure not only can realize optical-controlled switch function, but also can amplify the exchanged optical signal. The correctness of the 2×2 optical switch was verified by simulation on an OptiSystem simulation platform. Simulation shows that the signal to be connected was amplified from -10dBm to 16dBm, and the other signal was suppressed, and the extinction ratio was up to 26dB, by the control of 15dBm control optical pulse, and the switch speed exceeds 20Gbit/s.
