We investigate effects of different mechanisms on coupling efficiency between strip waveguides and the slow light mode in photonic crystal (PCWs). Both numerical simulations experimental results show that group index (ng) tapering improves strip-PCW butt-coupling when compared to a direct waveguide high-ng PCW. However, is even higher an intermediate low-ng PCW used couple from without ng tapering. Our suggest role evanescent more dominant efficient two PCWs with large mismatch.

Our theory shows that be balanced in nontrivial superlattice such superlattice-induced disturbance suppressed without compromising crosstalk....
