 note = {application/pdf, We demonstrate state-of-the-art slow light insilicon-on-insulator photonic crystal coupled waveguide, which allows slow light pulse transmission and its tunable delay by means of structural chirping. The key idea of this study is the application of a folded chirping profile to the structure, instead of the conventional monotonous chirping. It suppresses unwantedspectral oscillation caused by structural disordering and expands the tuning range. By post-processing an airhole-diameter- chirped device, we show that 0.9-ps-wide slow light pulses are delayed for 72 ps, corresponding to a buffering capacity of 80 bits. In a separate, unchirped device, we demonstrate a tunable delay by applying thermally induced index chirping. Here, a maximum tuning range of 103 ps and tunable capacity of 22 bits are obtained.},
