This is the home of the Ab-Initio Research Group space.To help you on your way, we've inserted some of our favourite macros on this home page. As you start creating pages, adding news items and commenting you'll see the macros below fill up with all the activity in your space.a Wiki for the research groups of Steven G. Johnson, John D. Joannopoulos, and Marin Soljačić at the Massachusetts Institute of Technology.
The purpose of this Wiki is threefold: 
- Document the computational software that we have developed for nanophotonics research.
- Give our group members an easy way to post information about their work.
- Provide a place for us to easily list upcoming meetings and events of interest.
Free computational software
- MIT Photonic Bands (MPB) — electromagnetic eigenmode solver
- Meep — finite-difference time-domain simulations
- Harminv — extraction of complex frequencies and amplitudes from time series
- libctl — Scheme/Guile-based scripting of scientific code (used as the interface for MPB and Meep).
- h5utils — visualization of HDF5 data files
- NLopt — nonlinear optimization library implementing many different optimization algorithms
- Cubature code for adaptive multidimensional integration of vector-valued integrands via the Genz-Malik algorithm.
See also FFTW, our FFT software.
We also have a list of Free nanophotonics software in addition to the programs developed at MIT.
