- Direct link to our class on Max: https://max.byu.edu/20191-phscs471/

- The syllabus and tentative schedule is available on Max. If you'd like a hardcopy you'll to print that out yourself.

Here are handouts for/from various class periods, to be updated throughout the semester.

- day 1 - What you should already know.pdf
- day 1 - equations to be given on exams.pdf
- day 5 - Complex numbers.pdf
- day 6 - Lorentz model derivation.pdf
- day 7 - The Power of the Lorentz Model.pdf
- day 8 - Derivation of Poynting's Theorem.pdf
- day 8 - derivation of s-polarization Fresnel coefficients.pdf - available as a hardcopy handout only, not via download. See me if you missed class when it was handed out.
- day 11 - converting T02 to more useful form.pdf
- day 12 - plots of T02 for various F's.pdf
- day 13 - multilayer examples.pdf
- day 15 - solving fresnel's eq for n in crystals - example 1.nb (Mathematica); day 15 - solving fresnel's eq for n in crystals - example 1.pdf (pdf)
- day 15 - solving fresnel's eq for n in crystals - example 3.nb (Mathematica); day 15 - solving fresnel's eq for n in crystals - example 3.pdf (pdf)
- day 21 - Fourier series and transforms.pdf

Old links from last semester; probably the handouts for this semester will be quite similar.

- day 22 - Dirac delta functions handout | Convolutions handout. Also, as mentioned in the handout, please play around with the convolution applet here to help develop your "convolution intuition".
- day 35 - Bessel functions handout

- Here are the "knife edge technique" data files, laser power vs. x. The file names indiate the location the knife edge was for each set of data, i.e. the z-value in mm. The x-values of the data files are also in mm.

- Here are several optics animations, many developed by Dr. Peatross as he was writing the textbook.
- Here's an animation illustrating what the free spectral range means. The
y-axis is the transmission of a Fabry-Perot interferometer with F = 100; the x-axis is
the separation distance d, going from 0.9999 cm to 1.0001 cm. One plot (the
blue curve) is for lambda = 500 nm. The other plot (tan curve) is for lambda
= 500 nm + (a small delta lambda), and the plot is animated based on the
value of delta lambda. The changing delta lambda is given in the plot label.
You can see what happens as delta lambda is varied from 0 to 2x the FSR of
0.0125 nm.

- Here are some exams from Winter 2008 semester for you to use as study aids. Important notes: (a) Some of the chapters were in a different order compared to the current version of the book, so the exams didn't cover things in the same order. (b) There were only two midterm exams, rather than three. That also changed the coverage per exam.
