    "abstract": "Lasing at telecommunication wavelengths from annular resonators employing\nradial Bragg reflectors is demonstrated at room temperature under pulsed\noptical pumping. Sub milliwatt pump threshold levels are observed for\nresonators with 0.5-1.5 wavelengths wide defects of radii 7-8 mm. The quality\nfactors of the resonator modal fields are estimated to be on the order of a few\nthousands. The electromagnetic field is shown to be guided by the defect. Good\nagreement is found between the measured and calculated spectrum.",
