cos R(0) = sin sin O cos slow QWP P slow fast QWP 45⁰ -45⁰ fast X c) The image above right shows a compound device comprising two QWPs and a linear polarizer with its transmission axis indicated by vector p. (i) Show that the Jones matrix for this optical train can be written [3] 1 /i Jerain = (17¹). (ii) By calculating its effect on the general incident polarization state (8), Or or otherwise, find the purpose of this compound device. [3] d) x polarized light with intensity I is passed through the device before hitting a mirror at normal incidence. (i) Calculate the field and intensity incident on the mirror. [4] (ii) If the light source is a narrow beam from a 3 mW laser, calculate the force on the mirror. [3] (iii) What intensity is transmitted back through the compound device after reflec- tion from the mirror? [3]
