PHYS 402 :: Physics Illinois :: University of Illinois at Urbana-Champaign

Course Description

Physics 402 is a comprehensive course on the fundamentals of (mainly) classical optics, covering concepts in geometrical optics and action principles, matrix techniques for ray tracing, mechanics of classical waves with emphasis on energy and momentum, radiation, light in matter and optical dispersion, polarization effects such as birefringence, wave packets, optical modulators such as phase retarders, interferometry, Kirchhoff and Fresnel theories of diffraction, nonlinear optics, holography, and basic concepts in quantum optics.

This course is aimed at advanced undergraduates and graduate students in Physics, Chemistry, Materials Science, and other areas of science or engineering, who plan to pursue research or a career in optics or who simply are interested in deepening their knowledge of the subject. The purpose of this course is not to teach all of optics, which could never be covered in a single course, but to cover the foundations of the subject in enough depth to prepare you for any area of specialization.

Text

Optics, 5th Edition, Eugene Hecht (4th Edition is also acceptable)

Lectures

Lecture will be given in Loomis 151 MW 11:00AM-12:20PM for a limited number of students. Live lectures will also be available via Zoom and recorded. Links to both live and recorded lectures will be posted on the schedule section of the course website. Lecturer's notes will also be posted there; these notes are meant to be used as a reference to the material covered at the lecture and not to replace your own notes. Please read the assigned sections in the text before class (see schedule). Lectures are inspired by the text but will take a different treatment of some of the topics.

Homework

The homework will be posted in the schedule section of the course website. Please upload completed homework to the Phys 402 course server (you may use the Submit link) by the due date and time (typically midnight). The due date will be indicated in the homework file. Late homework will not be accepted unless prearranged with the course director.

Labs

Every student will be assigned to perform five distinct lab experiments. Each lab takes two sessions (i.e., 2 weeks) to complete. The labs are a real treat and a chance for you to see a real-life manifestation of topics we discuss in lecture.

Please comlete the laser safety training on the DRS (Division of Research Safety) website https://www.drs.illinois.edu prior to your first laboratory class!

An acceptable lab writeup should have the following components:

  1. Abstract: Single paragraph on the purpose and conclusions of the experiments performed in the lab. Please do not plagiarize the purpose/introduction sections from the lab manual.

  2. Apparatus/Instrument: Should include a diagram of the experimental set up with the critical components labeled. Explain the basic principles behind how the instrument works.

  3. Procedure: Write down what you did, for example how you aligned the instrument, samples you made, and data you took. If it isn't immediately clear (as judged by your lab TA) where the measurements you report came from you may not receive credit for the lab.

  4. Results and Discussion: Present raw data, graphs, calculations. Show one clear example calculation if you have to compute a value based on the measurements. Include units. If there was a pre-lab, include answers at the beginning of this section. Did your results match what you expect? What were the sources of error? Can the experiment be improved?

Please submit lab writeusp by uploadeding them to the Phys 402 couse server (you may use the Submit link). Writeups should be about 5-10 pages in length, which is once a diagram of the apparatus, the raw data, and the calculations are included, is a lot less space than you might think. Labs are pass/fail, and you pass as long as you made a "good faith" effort to complete the lab, and your lab report demonstrates a reasonable understanding of what happened. 

Exams

The Midterm exam will be accessible online only during class time (see schedule). The final is 180 min (date and time TBA). More informaion about exam procedures, allowed material, and time TBA.
