  1. Through the Looking Glass and What We Found There E B k Reduced phase velocity: nAbsorption: k

  2. TE TM TM TE internal reflection:n = 0.667 external reflection:n = 1.5

  3. variable phase TE TE TM TM internal reflection:n = 0.667 external reflection:n = 1.5

  4. write r in this form: Why? Because: phase shift = 2a

  5. Great, but what is a? TE:

  6. TM TE TM-TE Phase shift upon total internal reflection: TM TE Tunable phase lag based only on dielectric reflections!

  7. The Fresnel Rhomb: linear glass circular

  8. Phase Retarder “birefringence” A dependence of the index of refraction on polarization (anisotropy in n). Jones:

  9. Jones matrix: Phase Retarder circular or elliptical SA linear Phase shift between H and V.

  10. 1/8 WP QWP FA polarizer SA TA Phase Retarder

  11. Jones Matrix: Rotator rotate by b linear “optical activity” Rotation of linearly polarized light as it travels through a material.

  12. “optical activity” r = Specific rotation: 10’s – 100’s degree/mm (depends on wavelength) RCP + LCP = linear nL> nR Optical activity can be thought of as the result of circular birefringence!

  13. Manipulating Polarization: Dichroism Birefringence Linear Circular
