    Description

    A domestic team in the present proposal has so far proposed an ultra-small and ultra-fast symmetrical
    Mach-Zehnder (SMZ)-type all-optical switch (PC-SMZ) based on two-dimensional photonic crystals (2DPCs)
    and optical non-linear quantum dots (QDs) for the future WDM/OTDM system, and demonstrated basic
    technologies inevitable for the PC-SMZ, such as ultra-low propagation loss, excellent directional-coupler and
    inter- ferometric optical-switch functions. An oversea team has, on the other hand, proposed an innovative
    2DPC simulation method, i. e., topology optimization (TO) method and remarkably improved bandwidth and
    transmittance properties of 2DPC waveguides. The current proposal involves complementary international
    collaborations based on these excellent results for establishment of an excellent 2DPC design technology for
    innovative ultra-small and ultra-fast optical switch with a latch function. The result is definitely thought to
    pave the road to a optical logic element inevitable for the future photonic net work system.
