    "abstract": "We describe a general recipe for designing high-quality factor (Q) photonic\ncrystal cavities with small mode volumes. We first derive a simple expression\nfor out-of-plane losses in terms of the k-space distribution of the cavity\nmode. Using this, we select a field that will result in a high Q. We then\nderive an analytical relation between the cavity field and the dielectric\nconstant along a high symmetry direction, and use it to confine our desired\nmode. By employing this inverse problem approach, we are able to design\nphotonic crystal cavities with Q \u003e 4*10^6 and mode volumes V ~ (\\lambda/n)^3.\nOur approach completely eliminates parameter space searches in photonic crystal\ncavity design, and allows rapid optimization of a large range of photonic\ncrystal cavities. Finally, we study the limit of the out-of-plane cavity Q and\nmode volume ratio.",
