Episodes (22)
Birefringence
We look at birefringence in crystals and discuss optical activity and the Faraday effect.
Polarization of light
We look at the vectorial nature of light and describe polarization in terms of Jones vectors
Diffraction from Double Slits
Diffraction from a double slit is discussed. The convolution theorem is presented and the grating equation is derived. (incomplete)
More Diffraction
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
We look at Fraunhofer diffraction from a slit and for a Gaussian beam. We use Huygen's principle and also discuss Babinet's principle
More Fiber Optics
We discuss unconventional types of fibers including photonic crystal fibers
Fiber Optics
We introduce the basic principles and parameters associated with fiber optics
Coherence
We introduce the coherence function and look at the relationship between coherence, bandwidth and linewidth.
Fourier Analysis
Fourier Series are introduced and are generalized to the Fourier sine and cosine tansform
Fabry-Perot Interferometer
We look at the transmission of a Fabry-Perot interferometer and discuss properties like the free spectral range, finesse and linewidth.
Michelson Interferometer
We investigate the Michelson interferometer and the relationship between physical parameters and the interference term.
Two beam interferencde
We look at the interference term present when two waves interfere and discuss the effect coherence has on fringe visibility
Group and Phase velocity
We look at the difference between group velocity and phase velocity in a dispersive material and introduce the Fourier transform
Superposition
We investigate the behavior of multiple waves that overlap in space and time.
Wave equation
We look at Maxwell's equations and use them to find the wave equation for electromagnetic radiation. We then investigate various solutions to the wave equation.
Thick Lenses
We introduce thick lenses and discuss parameters necessary to describe them. We go on to introduce ray matrices.
Ray Matrices
We look at methods for solving imaging problems using ray matrices.
Thin Lenses
We introduce the thin lens equation and the lens makers formula and the concept of ray tracing.
Fermat's Principle and Huygen's Principle
We Introduce Huygen's principle and Fermat's principle and use them to derive Snell's law and the law of reflection.
