Abstract

We show that it is possible to confine light in a volume of order 103 cubic wavelengths using only dielectric material. Low-index (air) cavities are simulated in high-index rod-connected diamond photonic crystals. These cavities show long storage times (Q-factors >106) even at the lowest volumes. Fabrication of such structures could open a new field of photon-level interactions.
