Textbook

Introduction to Optics by Pedrotti&Pedrotti&Pedrotti, 3rd Edition, Prentice Hall. ISBN: 978-0131499331

Course description

Optical products are all around us: from laser printers and cell phones, to CDs and telecommunication fibers. This trend is to continue increasingly. Indeed, it is said that the 21st century will be photonics dominated.

 

Optics is the study of light, which we now know consists of a light “particle” called photon. In other words, optics is really the study of a single particle, photon. Now, that might strike you as a simple thing to do, but hear what Einstein said:

“Many physicists think they know what a photon is. I have spent a lifetime working on it but I still don’t know what a photon is.”

 

In this course, we will be learning about various aspects of light, and at the end of it, evaluate Einstein’s remarks. Particularly, we will study geometrical, physical, and quantum optics. Lasers will be especially a central part of this course: we will learn about their physics, and do experiments with them.

 

Out of the two weekly lectures, there will be one lecture  (mostly) on Mondays, and one lab session (mostly) on Thursdays. Homework assignments and conceptual surveys will be given regularly, so be abreast with the course material. There will be two midterms and a final examination. Experiments will be conducted in groups of 3 or 4. You will be required to write separate lab reports for the first three labs, and one single lab report for the whole group after that. The lab reports will be due exactly one week after the experiment has been performed. A crucial part of lab reports will be the error analysis. I will describe to you how you can do that. For other info and detailed grade scheme see below.

 

If you have a specific disability that qualifies you for academic accommodations, please contact Disability Services for letter of accommodation. 

Attendance policy

You cannot miss any lab without a valid excuse such as sickness or a family emergency. For the former you have to bring in a note from your doctor.

Course Learning Objectives:

At the end of the semester, the Phys 320 students will acquire the following knowledge and skills:

Familiarity with and facility in experimental technique. This entails learning how to:

(i) Follow written directions.

                  (ii) Analyze experimental results.

                  (iii) Design one's own experimental procedures.

                  (iv) Determine whether an experimental design is "good" or "bad".

                  (v) Use sophisticated equipment.

                  (vi) Construct apparatus.

Familiarity with and facility in the use of computers and modern computing techniques for:

                  (i) Analysis of data.

                  (ii) Numerical solution of problems.

                  (iii) Interfacing with experiments.
