Abstract

A slab two-dimensional photonic crystal in diamond is being considered for quantum information processing. In view of the low refractive index of diamond, the question whether a high Q cavity is achievable has to be addressed. Here, various geometrical designs of single point defects and double heterostructures for the formation of high Q nanocavities in diamond are modeled. The highest value of vertical quality factor $Q_{v}\sim 70\,000$ was achieved in double heterostructures. This result seems to be significant for further consideration of photonic crystals in diamond for quantum electrodynamics applications.
