Microcavities offering small modal volumes V approximate to 0.6 (lambda/n)(3) and consisting of two identical tapered Bragg mirrors etched into a monomode silicon-on-insulator ridge waveguide are studied for operation at telecommunications wavelengths. The authors have measured a Q factor of 8900, for a loaded cavity with a peak transmission at resonance in excess of 60%. The measured Q value quantitatively agrees with the calculation results and is 20 times larger than those previously reported for similar geometries without tapers.
