Location:  Harvill 211
 

Course description
    OPTI 511 is an introduction to basic concepts of optical physics and the interaction between light and matter.  This course is designed to give optics students a broad understanding of the generation and absorption of light by matter,  and how light can be used to manipulate properties of matter and be manipulated by matter.  In this course, basic ideas from quantum mechanics will be introduced and used to develop the concepts of atom/light interaction, and the quantum nature of atoms and optical fields will be explored.  The basic properties of lasers will be briefly discussed in a few lectures near the end of the semester.  Please note that this course no longer covers an introduction to nonlinear optics.
    While previous courses in physics would indeed be helpful, this course is designed to be accessible to students who have a general science or engineering background and basic familiarity with using complex numbers, matrices, and differential equations.   Previous courses in quantum mechanics are NOT needed.

 

Course emphasis
    Because this is an introductory course covering many topics, this course will not develop detailed exploration of the subjects that will be covered. If you have further interest in any of the course topics, other specialized classes cover the subjects in detail.  In this respect, OPTI 511R covers material that is fundamental to many other Optics courses in quantum optics and photonics.  In OPTI 511R, an emphasis will be placed on the learning of new concepts, rather than detailed mathematical derivation of all of the subjects. Many of the concepts of quantum mechanics and quantum optics may seem strange and nonintuitive. For some of these concepts, an initial (perhaps tentative) acceptance will be needed until they become more familiar.  The math used in this course is generally not difficult. However, learning the mathematical formalism and the application of the mathematical tools can be tricky and confusing. Many simple tricks and approximations exist to solve problems, some of which we will explore. 
    The language of optical physics and quantum mechanics can also be confusing at times. Previously familiar words take on new meanings or new mathematical formalism, and a single concept can have various mathematical representations or notations on paper. As in most scientific disciplines, different authors and instructors use different symbols to represent identical concepts. In this course, it is the concept that is of primary importance; given a symbol or a problem, you must interpret the expression or method to solve the problem, and extract the relevant concepts.

 

Recommended texts          
    This class does not have a required textbook.
    The recommended textbook is "Introduction to Quantum Mechanics" by David Griffiths (Prentice Hall, 1995).  This book will be paralleled  for about half of the semester as the concepts of quantum mechanics are introduced and developed, and until the basic properties of light/matter interaction have been introduced.  If you have never had a course in QM, and are serious about learning this topic, this is an excellent book for learning the basics of QM.  If you have had a QM course, you will probably find that the class notes or other QM reference books are fine.  Thus, this is not a required textbook.  Please note that while many subjects, notations, and problems between the book and the lectures will be similar or identical, it will be each student's option to follow along in the book, find and read the relevant sections, and work example problems as needed.
   
 There will also be a set of notes printed by Fastcopy at the University of Arizona, and available at the Bookstore, that will be sold for a small amount (maybe $25 or so).  These are the instructor's handwritten lecture notes for the course, and will be closely followed for the entire semester.  These notes are a good refresher if you have had brief exposure to quantum mechanics, but if you're learning QM from scratch, you may find Griffiths additionally helpful.  There are also many topics that are covered in the notes, and not in the book.  It is strongly suggested that all students purchases a set of lecture notes from the UA Bookstore at the beginning of the semester.   To purchase the notes, ask for the following:
    Course#: OPTI 511R
    Instructor: Anderson
    Title: Optical Physics and Lasers
    Author: Anderson
    Semester/Year: Spring 2006.

    Distance-learning students especially need to purchase a set of notes, since the material written on the blackboard may not always be visible or resolvable.   If you are not in Tucson, you can use this link to order the lecture notes through the UA Bookstore. Purchases from distance learning students need to have two specifics in their request:
    1. Check “Yes” when the electronic form asks for class notes, or else the notes cannot be pulled up from the system, and
    2. Write “Distance Learning student, long distance shipping requested” in the Comment field.

        Homeworks:  weekly.

Prereqs: OPTI 501 and basic linear algebra
        Particularly, it is assumed that the following concepts will be familiar:
            1.  Wave equation and complex representation of EM waves
            2.  Lorentz oscillator model, absorption, and refractive index
            3.  Basic operations with vectors and complex variables

            7.  Separation of variables method of solving partial differential equations
        Topics 1-5 above are especially important.  If you are weak in any of these areas, you may need to do some extra work during the course of OPTI 511.  Some key ideas will be reviewed, but these topics will not be taught from scratch.
        Again, previous courses in physics will be helpful, but are not required.  This course is designed to be accessible to students without a physics background.
