    "abstract": "We derive a coupled mode theory for the interaction of an optical cavity with\na waveguide that includes waveguide dispersion. The theory can be applied to\nphotonic crystal cavity waveguide structures. We derive an analytical solution\nto the add and drop spectra arising from such interactions in the limit of\nlinear dispersion. In this limit, the spectra can accurately predict the cold\ncavity quality factor (Q) when the interaction is weak. We numerically solve\nthe coupled mode equations for the case of a cavity interacting with the band\nedge of a periodic waveguide, where linear dispersion is no longer a good\napproximation. In this regime, the density of states can distort the add and\ndrop spectra. This distortion can lead to more than an order of magnitude\noverestimation of the cavity Q.",
