Abstract
Optical waveguides formed from coupled ultrahigh-Q cavities are investigated by finite difference time domain (FDTD) simulation. Ultra high group velocity dispersion together with a group velocity as low as 3×10−5c is predicted at the band edge. It is shown that full compensation of the group velocity dispersion for chip free slow light (~c/100) over a bandwidth of 230 GHz is possible using a coupled cavity waveguide comprising cavities of Q ~ 106.
