Polarizers and a Quarter-Wave Plate
A monochromatic laser beam of intensity Io = 659 W/m2 is polarized in the y-direction and propagates in the positive z-direction. This beam is incident upon a quarter-wave plate whose fast axis makes an angle of 45 degrees with the x-axis as shown. Following the quarter-wave plate are two polarizers; the transmission axis of the first polarizer is aligned with the x-axis, while the transmission axis of the second polarizer makes an angle of θ1 = 72 degrees with the...

Most popular application of wave plates is that they can act as polarization rotators when the phase retardation is a (Half-Wave Plate, HWP). Show from Jones matrices that linearly polarized light after passing through a HWP is still linearly polarized but with a different direction of polarization. What is the angle of rotation for linearly polarized light with an inclination angle of 0 (e.g., relative to the fast axis FA)?

A linearly polarized electromagnetic wave has an average intensity of Io. This wave is incident on a polarizer. What angle between the axis of polarization of the polarizer and the direction of polarization of the incident light will result in an average intensity of light leaving the polarizer of 0.51.10?

Draw what the E-field vector (and thus the polarization) looks
like for linearly polarized light, at eight equally-spaced times in
the light's period (i.e. at phase angles 0∘, 45∘, 90∘, 135∘, 180∘,
225∘, 270∘, and 315∘). Include both direction and magnitude (see
figure below).
Repeat this for circularly and elliptically polarized
light.
