    "abstract": "A two-dimensional photonic crystal semiconductor microcavity with a quality\nfactor Q ~ 40,000 and a modal volume Veff ~ 0.9 cubic wavelengths is\ndemonstrated. A micron-scale optical fiber taper is used as a means to probe\nboth the spectral and spatial properties of the cavity modes, allowing not only\nmeasurement of modal loss, but also the ability to ascertain the in-plane\nlocalization of the cavity modes. This simultaneous demonstration of high-Q and\nultra-small Veff in an optical microcavity is of potential interest in quantum\noptics, nonlinear optics, and optoelectronics. In particular, the measured Q\nand Veff values could enable strong coupling to both atomic and quantum dot\nsystems in cavity quantum electrodynamics.",
