摘要:
In this paper, a general analysis for non-linear micro-ring resonator as all optical switch is discussed in a vertically coupled GaAs-AlGaAs micro-ring resonator by carrier injection. The ring resonator is optically pumped, which results in temporal shift of resonant wavelength by refractive index change due to carrier injection. A green laser as optical pump beam is used to shift resonant wavelength 1.5 nm of the ring resonator. Simulation, analysis and overall transfer function of single ring as well as cascaded micro-ring resonator (MRR) is studied. A single circuit, consisting of three MRRs, capable to perform all the two input sixteen logic operations is studied and reported. The same circuit can also act as half adder/subtractor and single bit data comparator. (C) 2013 Elsevier GmbH. All rights reserved.
