    "abstract": "A novel class of circular resonators, based on a radial defect surrounded by\nBragg reflectors, is studied in detail. Simple rules for the design and\nanalysis of such structures are derived using a transfer matrix formalism.\nUnlike conventional ring resonators, annular Bragg resonators (ABR) are not\nlimited by the total internal reflection condition, and can exhibit both large\nfree spectral ranges and low bend losses. The Bragg reflection mechanism\nenables the confinement of light within a defect consisting of a low refractive\nindex medium (such as air). Strong atom-photon interaction can be achieved in\nsuch a structure, making it a promising candidate for sensing and cavity QED\napplications. For sensing applications, we show that the ABR structure can\npossess significantly higher sensitivity when compared to a conventional ring\nresonator sensor. Lasing action and low threshold levels are demonstrated in\nABR lasers at telecommunication wavelengths under pulsed optical pumping at\nroom temperatures. The impact of the intensity and dimensions of the pump-spot\non the emitted spectrum is studied in detail.",
