Lasing threshold for whispering-gallery-mode microsphere lasers

Ying Wu, P. T. Leung

The analytical expression for the lasing threshold for whispering-gallery-mode microsphere lasers under the strong-coupling condition is obtained by solving a quasi-three-level quantized model. It explicitly displays the dependence of the lasing threshold on the cavity radius, the homogeneous linewidth, the quality factors and linewidths of the relevant cavity modes.

High gain selective amplification in whispering gallery mode resonators: analysis by cavity ring down method

Patrice Féron, Alphonse Rasoloniaina, Vincent Huet +6 more

We study both theoretically and experimentally the dispersive properties of single whispering gallery mode resonators. We present a simple experimental protocol which allows us to obtain in detail its coupling regime and thus their dispersive properties. We demonstrate a compact optical amplifier with a gain up to 20dB in an Erbium doped fluoride microsphere of 135μm in diameter coupled via a tapered fiber. The model is also applied to analyze the dynamic behavior of the modal coupling between two degenerate resonances of the same cavity. In particular, this can be used to describe the coupling of counterpropagating whispering gallery modes (WGM) by Rayleigh scattering. The theory is successfully compared to experiments carried out in silica microspheres

Modulated Photon Emission of Eu 3+ in Microsphere Cavity

Yong Yang, Zheng‐Fu Han, Dong Chun-Hua +2 more

Fused silica microsphere with a few Eu 3+ ions on the equator is fabricated. The photon emission sharply modulated by whispering gallery (WG) modes is observed under excitation of 395 nm laser, which is in agreement with the prediction in theory. The quality factor of the WG modes in microsphere is estimated larger than 3000 from the emission spectrum, which is limited by our monochrometer. It proves that pumping Eu 3+ in microsphere cavity in free space is feasible, and this system seems suitable for realizing strong coupling in future quantum computation purposes.
