Welcome to the the Nanostructures and Computation Wiki at MIT!


This is a Wiki for the Ab-initio Physics groups of John D. Joannopoulos, Steven G. Johnson, and Marin Soljačić at the Massachusetts Institute of Technology.

The purpose of this Wiki is twofold:

  • Document the computational software that we have developed for nanophotonics research.
  • Give our group members an easy way to post information about their work.

In particular, any user of our software is encouraged to help in adding documentation, tips, tricks, and examples — just register for a user name and log in. (Pages specific to our MIT researchers, on the other hand, will generally only be editable by us.)

Free computational software

  • MIT Photonic Bands — electromagnetic eigenmode solver
  • MEEP — finite-difference time-domain simulations
  • Harminv — extraction of complex frequencies and amplitudes from time series
  • h5utils — visualization of HDF5 data files

How to edit

First, you must register for a user name and log in; anonymous edits are not permitted on this Wiki. Then, click on the edit button at the top of the page. We use the MediaWiki software, which is the same as the Wiki software that runs Wikipedia — detailed instructions on how to edit and format pages can be found at:

The Wikipedia Help Pages.

To practice editing, try editing in the Sandbox.

You can link to a Wikipedia article by prefixing "w:" to a link, as in w:Photonic crystal. Users looking to write general articles not specific to the MIT software should go to Wikipedia instead of here.

MIT users should contact —Steven G. Johnson to obtain administrative privileges, so that you can protect pages on your personal work from editing by the general public.
