We look at how the various pieces of optics we have studied throughout the course are integrated in to devices.

Physics 208

Photonic Circuits

We look at generation, propagation and detection of ultrafast laser pulses

Ultrafast optics

We look at the third order nonlinear effect and uses for Kerr lenses.

4 wave mixing

We use coupled mode analysis to investigate the field amplitudes in three wave mixing, and look at the effect of phase mismatch on the conversion efficiency of nonlinear processes.

Nonlinear Wave Equation

We look at the phase matching condition for Second Harmonic Generation and also do a tuning curve example for an OPO

Phase Matching of SHG

We introduce non-linear optics and discuss various forms of 3 wave mixing including frequency converters, optical parametric amplifiers (OPAs), optical parametric oscillators (OPOs) and second harmonic generation (SHG)

Nonlinear optics 1

We generalize the expressions for 1D waveguide to 2 dimensions and focus on the calculation of power coupled into a waveguide from a Gaussian beam.

2D Waveguides

We look at both the ray picture and field picture of modes in a 1D waveguide.

1D waveguides

We look at the unusual properties of 2d and 3d photonic crystals

Photonic Crystals

We look at Bloch Wave solutions to propagation in a periodic material using Fourier analysis of the material permittivity.

Propagation in periodic media

We introduce the electrooptic tensor and do examples using the linear electrooptic effect.

Electrooptics

We look at figures of merit for acoustooptic materials and limitation on modulation bandwidth in acoustooptic modulators.

Acoustooptic devices

We look at the Bragg condition in anisotropic materials and solve for the diffracted beam amplitude using coupled mode theory.

Acoustooptics

We introduce Jones calculus to keep track of polarization direction and use it to describe a number of examples including polarization rotation in a twisted nematic liquid crystal.

Jones Calculus and Liquid Crystals

We look at how aspects of this class relate to the Laser Interferometer Gravitational Wave Observatory (LIGO) and investigate the design of the LIGO Faraday Isolators

Faraday Rotators in LIGO

Class material from Physics 208 "Electrooptics" at San Jose State for Spring 2009. This podcast will mostly contain recorded lectures in m4a format.
