We have proposed the all-optical interconnection, in which the photorefractive four wave mixing (FWM) is used as the core, by full-linear resonator (FR) with a beam splitter (BS) and a self-pumped phase conjugate mirror (CAT). The index grating of the FWM region inside the photorefractive crystal (PRC), which determines the connection pattern, was maintained by the rewriting effect of the input signal beam and the resonance beam between the CAT and the BS. But the power of the resonance beam was wasted by the optical reflection at the crystal surface of the CAT and the PRC. Therefore the rewriting effect of the connection pattern could not be obtianed sufficiently. In this report, we propose the integrated full-linear resonator (IFR), in which a self-pumped phase conjugation (SPPC) region and the FWM region are formed in one PRC, to solve this problem. Compared with the conventional FR, the power loss of the resonance beam by the optical reflection can be prevented and the resonance beam can be used efficiently for the maintenance of the connection pattern. We experiment on the 2×2 all-optical interconnection with the IFT by using BaTiO3 crystals and Ar+ laser. It is shown that the maintenance time of the connection pattern can be extended sufficiently by using IFR.© (2003) COPYRIGHT SPIE--The International Society for Optical Engineering.

We propose an all-optical interconnection with pattern memory function by a photorefractive full-linear resonator with a beam splitter(BS) and a self-pumped phase conjugate mirror(CAT). This interconnection utilizes the oscillation phenomenon between the BS and the CAT. This resonance beam rewrites and sustains the connection pattern continuously, which is once configured by the writing beam, after the writing beam is turned off. We analyze the optimum reflectivity of the BS and the CAT, which determines the feedback rate of the resonation, for high connection efficiency. We also analyze the coupling strength threshold of the photorefractive crystal for the sustentation of the connection. We experiment on the photorefractive full-linear resonator in order to examine the efficiency and the sustentation time of the connection.
