FIG. 1.

(a) scanning electron microscope image of a spiral-shaped microcavity disk laser diode with a disk radius of for . (b) The side view of the fabricated laser. (c) The measurement of the laser output with a fiber. The inset figure in (a) is the perimeter of the cavity.

FIG. 3.

Optical spectra of near field intensity, is the (a) spectrum for the two cases of the pumping current: the lower trace (A) is the power spectrum at and the upper trace (B) at . In the upper trace, we can see periodic sharp peaks. (b) The enlarged spectrum in order to see the mode spacing.
