    We present design and FDTD simulations of microring resonator array optical buffer. The proposed buffer consists of six microring array coupled via upper MZI arm and one microring coupled via lower MZI arm all coupled with 105 nm gap coupling. Results obtained have shown that the delay signals can be available for the use for optical memory and applications.

    We present the design and FDTD simulations of microring resonator array optical buffer. The proposed buffer consists of six microring array coupled via upper MZI arm, and one microring is coupled via the lower MZI arm, where all coupling gap used is with 105 nm. Results obtained have shown that the delay times of the output signals can be used to form the optical buffer(memory), which can be available for high capacity channel multiplexing and filtering applications.

    Proposed nonlinear microring resonator arrangement for stopping and storing light
    (2009-03-15)

    A simple system of an all-optical system for stopping and storing is proposed. A system consists of two microring and a nanoring resonators that can be integrated into a single system. The large bandwidth is generated by a soliton pulse within a Kerrtype nonlinear medium where an all-optical adiabatic and pulse bandwidth compression can be performed. The balance between the dispersion and nonlinear lengths of the soliton pulse exhibits the soliton behavior known as self-phase modulation, which produces a constant optical output. This means that light pulse can be trapped, i.e., stopped optically within the nanowaveguide. © 2009 IEEE.
