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.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
