Wedescribe a tunable slow light device based on a photonic-crystalwith a mechanically adjustable coupled-resonator optical waveguide structure. The lateralenergy confinement is implemented along a lattice shear defect withthe group velocity actively controlled by shifting the shear alongthe defect interface over a distance of one crystal period.The group velocity tuning range can be anywhere from arbitrarilysmall (determined by the waveguide structure) to near the valueexpected in bulk media. We present the theory and ademonstration (via simulation) of a device configuration that is realisticto fabricate and achieves a tunable range of group velocityspanning at least three orders of magnitude. The conditions forstopping the light are also discussed for different configurations.
