2. A circularly polarised light beam is passing through linear polariser rotated to an angle 0. a) Assuming that the amplitude is normalised to 1, what is the Jones matrix of the circularly polarised light beam (either CW or CCW will be acceptable). [2] b) If the Jones matrix of the rotated polariser is given by ( cos20 sin 0 cose\\ sin 0 cose sin20 ), calculate the Jones vector of the output beam. Describe the physical meaning of the output vector.[4] (c) Calculate the optical power exiting the polariser and show that it is independent of the angle of the polariser. [4]
