Modulators

2008-05-0601:00:14

We look at the behavior of electrooptic devices as amplitude and phase modulators.

Birefringence

2008-05-0101:10:20

We look at birefringence in crystals and discuss optical activity and the Faraday effect.

Polarization of light

2008-04-2456:42

We look at the vectorial nature of light and describe polarization in terms of Jones vectors

$Diffraction from Double Slits$

Diffraction from Double Slits

2008-04-1518:26

Diffraction from a double slit is discussed. The convolution theorem is presented and the grating equation is derived. (incomplete)

$More Diffraction$

More Diffraction

2008-04-1053:17

We look at the relationship between far-field (Fraunhofer) diffraction and the Fourier transform, and explore the diffraction pattern of a uniformly illuminated circular aperture, which leads to the Rayleigh criterion for resolution in an optical system.

$Diffraction$

Diffraction

2008-04-0801:15:07

Fourier Analysis

2008-03-1801:15:55

Fourier Series are introduced and are generalized to the Fourier sine and cosine tansform

Fabry-Perot Interferometer

2008-03-1301:16:09

We look at the transmission of a Fabry-Perot interferometer and discuss properties like the free spectral range, finesse and linewidth.

Michelson Interferometer

2008-02-2801:15:35

We investigate the Michelson interferometer and the relationship between physical parameters and the interference term.

Two beam interferencde

2008-02-2601:14:37

We look at the interference term present when two waves interfere and discuss the effect coherence has on fringe visibility
