Abstract :
We analytically investigate the dynamic behaviors of the proposed optical XNOR and AND logic gate devices, with an monolithically integrated highly stacked InAs quantum dots structure SOA fabricated with the strain compensation technique and ring resonators. The calculated results indicate that the optical logic device can operate the logic gate functions at 160Gb/s RZ signals with large eye opening, the value of which is estimated to be 90.3%, as compared to the bulk-type SOA. And we show the potential of this device for routing signal processing in ultra-fast photonic network system.
