matlab-polarization-photonics

A small collection of .m's that I've used in photonics experiments.

Getting Started

Pull the master branch of this repository and ensure your MATLAB working directory can see each of these files if you seek to use them.

Generally Useful Content

These files could be generally useful for engineers working with polarization optics.

• gaussFit.m - Fits gaussian parameters mu (mean) and sigma (std) to a normal-like distibution.
• calcFidelity.m - Calculates the quantum fidelity between two density matrices.
• calcPurity.m - Calculates the quantum purity of a density matrix.
• PlotPS.m - Plots a single Stokes vector on the Poincare Sphere.
• jVec2sVec.m - Computes a Stokes vector from a Jones vector.
• sVec2ell.m - Compute elliptical parameters (orientation, eccentricity, semi-major-minor axes lengths) from Stokes vector.
• stokes2DensityMat.m - Covert a Stokes vector to a density matrix

Full Content

• PlotPS.m - Plots a single Stokes vector on the Poincare Sphere.
• StokesPolarimetry.m - Perform Stokes polarimetry to characterize a general polarization state.
• calcFidelity.m - Calculates the quantum fidelity between two density matrices.
• calcPurity.m - Calculates the quantum purity of a density matrix.
• calcSNR_CCD.m - Calculates the signal-to-noise ratio from intensity data. Ideal for CCD cameras.
