pyLuminous Files

pyLuminous is the umbrella project that currently contains pyQW and pyFresnel. 
So downloading pyLuminous gives you everything.

pyQW is a python script for modelling a simple finite quantum well and its 
intersubband transitions. There is also a pdf included which goes through the theory.

pyFresnel is a collection of python modules for modelling the optical properties
of dielectric interfaces, slabs and thin films. 

pyFresnel includes a transfer matrix implementation that can also model the 
anisotropic intersubband transitions of a quantum well; these are anisotropic 
layers which interact differently with light polarised within the layer than with 
light polarised perpendicular to the layer.
