MASSACHUSETTS INSTITUTE OF TECHNOLOGY Department of Electrical Engineering and Computer Science 6.097 (UG) Fundamentals of Photonics 6.974 (G) Quantum Electronics Spring 2006 Quiz II Time: April 21 , 2006, 2-3:30pm Problems marked with (Grad ) are for graduate students only. This is a closed book exam, but two 81/2”x11” sheets (both sides) is allowed. At the end of the booklet there is a collection of equations you might find helpful for the exam. Everything on the notes must be in your original handwriting (i.e. material cannot be Xeroxed). You have 90 minutes for this exam. There are 5 problems for undergraduate and 6 problems for graduate students on the exam with the number of points for each part and the total points for each problem as indicated. Note, that the problems do not all have the same total number of points. Some of the problems have parts for graduate students only. Undergraduate students solving these problems can make these additional points and compensate eventually for points lost on other problems. Make sure that you have seen all 22 numbered sides of this answer booklet. The problems are not in order of difficulty. We recommend that you read through all the problems, then do the problems in whatever order suits you best. We tried to provide ample space for you to write in. However, the space provided is not an indication of the length of the explanation required. Short, to the point, explanations are preferred to long ones that show no understanding. Please be neat-we cannot grade what we cannot decipher. All work and answers must be in the space provided on the exam booklet. You are welcome to use scratch pages that we provide but when you hand in the exam we will not accept any pages other than the exam booklet. Exam Grading In grading of the exams we will be focusing on your level of understanding of the material associated with each problem. When we grade each part of a problem we will do our best to assess, from your work, your level of understanding. On each part of an exam question we will also indicate the percentage of the total exam grade represented by that part, and your numerical score on the exam will then be calculated accordingly. Our assessment of your level of understanding will be based upon what is given in your solution. A correct answer with no explanation will not receive full credit, and may not receive much-if any. An incorrect final answer having a solution and explanation that shows excellent understanding quite likely will receive full (or close to full) credit. 1
