Photonic crystal microcavities for chip-based cavity QED

摘要

The suitability of recently demonstrated high quality factor (Q), ultra-small mode volume (V-eff) graded square lattice photonic crystal microcavities for cavity QED experiments is discussed. In addition to the basic importance of the Q and V., of such cavities, other issues of both practical and fundamental relevance are considered. Included amongst these are the robustness of the cavity's performance to fabrication errors and the ability to efficiently source and collect light from the cavity through conventional fiber optics.
