Syllabus
 Optics syllabus
 Change: I have decided not to cover section 7.7. So please change the reading assignment for Feb 29 to be just sections 7.57.6.
 Change: There's a small change on dates on the syllabus. I will be out of town March 12 and March 14 instead of Mar 10 and Mar 12. We're going to switch the topics covered on the 10th and the 12th:
 Mar 10: Topic = Review (Ch 58). No reading assignment.
 Mar 12: Topic = Rays. Reading assignment is 9.1  9.3.
 Some major changes to schedule for chapters 10 and 11. Note in particular the reading assignment changes!

 notes  day 40.pdf  The last two pages of these notes are things we didn't talk about in class, but which might be interesting to some of you. The second to last page is some comments on that somewhatconfusinglooking graph for semiconductors, emitted wavelengths vs. lattice constant. The last page is my notes on longitudinal cavity modes, which we didn't have time to talk about. You won't be tested on the info. The most important item is that, approximating the cavity as a FabryPerot interferometer, you can show that only an integral number of halfwavelengths can fit inside the cavity. Thus lambda = 2L/n (L = length of cavity, n = integer); this puts a serious constraint on which wavelengths within the overall potential laser emission can in fact lase.
