摘要：

We have studied by phase modulation spectroscopy the whispering-gallery modes (Mie resonances) of 60 to 200 mum diameter microspheres obtained by fusing with a CO2 law the end of a high-transmission silica fibre. An evanescent wave at 780 nm was produced by total internal reflection of a phase-modulated semiconductor diode laser beam in a glass prism. It was coupled into the Mie mode of the microsphere positioned at a fixed distance from the prism face. The spectrum was obtained by measuring the phase-to-amplitude conversion of the laser beam modulation as its carrier frequency was scanned. Record Q-factors greater-than-or-equal-to 2.10(9) were observed, corresponding to photon storage times longer than 1 mus. Applications of these resonances to fundamental and applied projects are discussed.
