Revision as of 12:58, 20 January 2009

Course Information

Professor: Chip Durfee

Office: Meyer Hall 330

Meeting Times and Location: Alderson Hall 152: Monday, Wednesday, Friday 11:00-11:50

Office hours: tentative times - M12-2 and 3-5, F12-1. There some some recurring meetings I still have to set up, so these times may have to change. Looking at the schedules, there are no times that everyone is available, so I had to pick times to make sure that everyone had at least a couple of open hours.

Announcements

19 Jan: I have posted the slides from today, as well as a link to the paper that we're using as an example of an OPA. It's the paper by Brita in the journal section below.

10 Jan: Homework 1 is posted below.

If you are new to Mathematica, try doing the Wolfram screencast introduction, which you can find at http://url.wolfram.com/4enrnS/ I haven't tried this myself, but it's probably worth the time to help you get started. After going through that, feel free to come by during office hours to ask questions about working with Mathematica.

8 Jan: Welcome to the new Wiki page for Nonlinear Optics! The syllabus is posted below. You'll see an old Lecture Note 2007 section, that has scans of most of my notes from 2yrs ago. These will be revised and rescanned as we go, but it gives you an idea of what we will be doing.

Office hours

Office hours:

tentative times - M12-2 and 3-5, F12-1. There some some recurring meetings I still have to set up, so these times may have to change. Looking at the schedules, there are no times that everyone is available, so I had to pick times to make sure that everyone had at least a couple of open hours.

Course Forum, Supplementary Readings, Homework Solutions

open to class members only (auditors ok). If you aren't registered for the forum, follow the directions to register, email me your user name, and I'll put you on the list. Protected Documents for Nonlinear Optics

Lecture Notes 2007

These will be revised as we go along. Note that they are in Gaussian units, not SI. It looks like I had scanned just past halfway through the course. I'll see if I can find someone to help scan the rest.

Mathematica Demos

These aren't actually pdf's. Do a "save link as" to save these to your computer, then open with Mathematica.

2009 files

These downloads require Adobe Acrobat Reader Crystal_symmetries.nb: demonstrate effect of crystal symmetries, calculate angular dependence of deff. This has some examples of working with vectors and matrices in Mathematica.

2007 files (written in v5.2, but can be read into v6 or v7 and updated)

Links to literature in nonlinear optics

Each one of you should add references you think would be of general interest to this list - a minimum of one every other week. (Please note that this will be part of your grade...)

Click 'edit' at the right to add references. Include a short description, make a new category if it makes sense. Links only - don't upload actual pdf's please. Put your last name and posting date along with the citation.

Feel free to add to the list of database and journal sites

Database pages

Use these to go to papers where you know the reference, or for searching for related papers

Scitation: American Institute of Physics journals search

Optics Infobase: Optical Society of America journal search

CSM link to physics-related databases. In particular, try Web of Science (online Science Citation Index). This is the best resource for finding papers that are related to each other. I think our access goes back 10 years from present.

Google Scholar

You can go to these to browse current issues or to look up specific references. Journals in bold are (mostly European journals) not indexed through Scitation or Optics Infobase
