### COURSE: PHYS 411 - MODERN OPTICS

** INSTRUCTOR: ** Dr. Fearn

**TEXT:** " Optics", 2nd edition by E. Hecht (Addison Wesley)

Additional reading, "The quantum theory of Light", by R. Loudon Oxford press.

"Optical electronics" by A. Yariv, Holt-Saunders.
(or Quantum electronics, same author, Wiley).
"Modern Optics" by R. Guenther, Wiley.

You may also find the Schaum outline
books useful for optics and fourier analysis. You can ask at any time for
further references. This is a senior course so I am always open to
suggestions on the kind of material you want to cover towards the
end of the course, time permitting. My speciality is quantum optics.

### EXAMS/PROBLEMS:

There will be one midterm and a final exam, the midterm is worth 30% and
the final worth 40%. Problems will be assigned on a regular basis and will
be taken from the book and hand out problems. Each assignment will be
given to you in xerox form. Problems are worth 30%.
