Abstract
This paper proposes a simple scheme of four entangled photons generation using a pulse of weak light input into a Mach-Zehnder interferometer (MZI) incorporating a fiber optic ring resonator (FORR) without any optical pumping components included in the system. After a pair of entangled photon has been generated by a four-wave mixing of weak light pulse in the FORR [P.P. Yupapin, S. Suchat, Entangled photon generation using fiber optic Mach-Zehnder interferometer incorporating the nonlinear effect in a fiber ring resonator, Journal of Nanophotonics (JNP) 1 (2007) 013504], four and eight entangled photons can be performed. In application, the multi-entangled states can be formed using the appropriated coupling ratios into a fiber coupler. The effect of the entangled state walk-off along the optical fiber is discussed. © 2008 Elsevier GmbH. All rights reserved.
