Analysis and Simulation of Poincar#xe9; Sphere#x2014;Application to Ellipsometry

摘要

Elliptically polarised light is characterised by its azimuth and ellipticity. The sense of rotation of the ellipse described by the light vector can be represented geometrically by a point on a sphere called Poincar#xe9; sphere which enables us to visualise any changes in the polarisation state introduced by optically active devices unlike in an ellipsometric setup. Analysis of Poincar#xe9; sphere is carried out and an ellipsometric setup comprising of a polariser and analyser is studied and simulated with M#xfc;ller matrix technique with the polarisation state represented on the generated Poincar#xe9; sphere.
