Description:
This program is a set of scripts for simulating
and plotting atom-light configurations which produce electromagnetically
induced transparency.
Dependencies:
xmds2 and all of its dependencies, including the optional dependency numpy,
Octave
Usage:
Set simulation parameters in config.m
Open Octave in the eit_filter_simulations directory
Run config:
# config
Run simulate:
# simulate
Data files are stored by default in the data directory.
The naming convention is:
(ground state decay)_(drive intensity)_(1-photon detuning)_(ground state dephasing).h5
Data loading and plotting examples:
Plot 2-photon detuning vs absorption for a particular simulation:
# [detunings2, absorptions] = getSimulation('data/data_file_name.h5');
# figure;
# plotSimulation(detunings2, absorptions);
Plot width and transmission contrast vs drive intensity for given parameters:
# [drives, widths, min_absorptions, contrasts] = getSimulations('ground state decay', '1-photon detuning', 'ground state dephasing');
note:
you only need to specify these values to the decimal place that the file names change.
if you have:
0.001000_(drive)_1.000000_0.005000.h5
0.001000_(drive)_2.000000_0.010000.h5
0.001000_(drive)_2.000000_0.000000.h5
0.000100_(drive)_1.000000_0.000000.h5
and you want all data with:
ground state decay = 0.001,
1-photon detuning = 2,
ground state dephasing = 0
you would call:
# getSimulations('0.0010', '2', '0.000')
# figure;
# plotSimulations(drives, widths, contrasts);
Plot width and absorption vs drive intensity for given parameters:
Same as above except for the last line.
# plotSimulations(drives, widths, min_absorptions)
