Ultrahigh speed all-optical AND logic gate using integrated silicon-based MZI device

摘要

In this paper, we present a device with a silicon-on-insulator (SOI) based symmetrical Mach-Zehnder interferometer (MZI) structure to perform the ultrahigh speed all-optical AND logic gate function. Simulation results show that, while the operation speed is at a bit rate of 200 Gbit s−1, the output parameters including extinction ratio and eye-opening ratio for outcome AND logic gate signal can, respectively, reach as high as 12.8 dB, and 0.94 in the case of a 5 mm long SOI waveguide by means of judiciously adjusting the initial conditions, such as incident signal and probe continuous-wave (CW) powers.View full textDownload full textKeywordsintegrated optics, silicon-on-insulator technology, Mach-Zehnder interferometer, AND logic gateRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/09500341003692971
