Announcements
Your final exam marks are here
Your midterm,
labs, quiz1 and quiz2 marks are here
You can find the final exam under the table of
contents as a module "Final Exam" in Avenue. It is still empty and
you can access it only at 7:25 pm today. (Apr. 22).
You should be able to see a module “Final
Exam” in Avenue and also “Final exam submission” under Assessment ->
Assignment.
If you don’t see these modules on
Avenue, please contact the instructor. The final exam pdf will appear on the
module “Final Exam” at 7:25 pm on Apr. 22. It may be a good idea to download it
if you expect issues with the internet. Please answer those questions on paper
and upload the scanned version to the assignment dropbox
“Final Exam Submission” by 10:30 pm. It is better to keep 30 minutes for file
uploading. The instructor will be on
Microsoft Teams during the exam hours and you could post your questions on
Teams. If there are any issues/errors with questions, you will be notified on
Teams post/announcements will be made. So, please join Teams during the exam
hours. If you experience difficulty accessing the exam due to internet issues,
please email/text the instructor. The contact info is provided on Avenue.
You are allowed to refer to lecture
notes/textbook, but should not collaborate with other students. If we find two
exams to be similar, it will be considered academic dishonesty and your final
exam grade will be set to zero. The case will be transferred to the University
ethics committee.
Final Exam will be held on Apr. 22 from
7:30 pm – 10:30 pm (the same time as set by the registrar’s office). The exam
will be conducted on Avenue. The exam is two and half hours long and you get an
extra 30 minutes to upload your exam to Avenue. You may write on paper and then
scan your exam and upload. There will be 5 questions. The questions could be
either explain type or problem solving type. You are allowed to refer to
textbook/lecture notes, but not allowed to collaborate. I suggest you to keep a
formula sheet handy.
Exam review lecture will be held on Tuesday,
Apr. 7 from 5:30 pm – 7:00 pm. It will be a live stream. Exam format will be
discussed. Please attend this lecture on Microsoft teams. Sometimes recording
does not show the screen.
As discussed yesterday, the live
streaming is canceled and the instructor will record the lecture on Teams and
post the link on the course website. The
video is also available on Teams.
The recorded videos and
OneNote pdfs of the lectures on Mar. 19 or after are found under Lecture Notes -> Laser
-> videos.
If you had an issue with the faulty
equipment (for lab2) and your mark is impacted, please contact the TA Sayed
Ahmed, ahmes93@mcmaster.ca
The final exam for EE4EM4 will be on
Avenue. There will be 20 or 30 multiple-choice type questions. More details to
follow. Please login to Avenue in future for updates.
The online course hours:
Tuesdays, Thursdays and Fridays: 5:30 pm – 6:20 pm
The first lecture will start from Thursday, Mar. 19 at
5:30 pm. Please join the class on Teams by tomorrow.

The TAs will be available on Teams during their posted
office hours. If you have a question for a specific TA, please join the meeting
at that time or you can post on Teams.
Quiz3 is canceled. The quiz weight is determined by
the best quiz. For example, if you have got 8 for quiz1 and 9 for quiz2, your
quiz mark is 9.
The course is
now moved to Microsoft Teams:

Lab4 is cancelled
from Mar. 16. Those who did not get a chance to finish Lab4 - your lab weight
is based on the average of Lab1, Lab2 and Lab3.
For some of
you, you took a longer time to complete Lab2 and as a result, you did not
finish either Lab2 or Lab3. Given the situation, we will take the average of
the labs you have done and that will be your lab weight. For example, if you
have got 5 in Lab1 and 4 in Lab2, your lab weight is 4.5. You should have
finished at least two labs (i.e. (lab1 and lab2) or (lab1 and lab3)).
Quiz 2 will be
held during the tutorial on Thursday, Mar. 12.
Topic: Optical Fibers, focus is on dispersion
in single mode fibers, Fourier transforms and dispersion compensation. Please
go to the subsection Quizzes
below.
Lab4 will start
from Mar. 9 and run for two weeks. You will be doing Unit 4. Please follow your Mosaic
schedule.
Please go to
the midterm section to see the details on the format and topics.
There will be a
midterm review lecture on Tuesday, Feb. 25. The format of the midterm will be
discussed.
Some of you
faced problems in the lab due to malfunctioning of the equipment. The TA has
added some extra marks since it is not your fault.
Lab3 will start
from Feb. 24 and run for two weeks. You will be doing Unit 3. Please follow your Mosaic
schedule.
Quiz 1 will be
held during the tutorial on Thursday, Feb. 6.
Please go to
the subsection Quizzes
below.
A formula sheet will be provided at the end of questions. It would be similar
to that provided at the end of midterm (Please check the section Midterm Exam)
Lab2 will start
from Monday, Feb. 3 and will run for two weeks. You will be doing Unit 2
(Fibers). Please follow your Mosaic schedule.
Lab1 will start
from Monday, Jan. 20 and will run for two weeks.
Tutorials will
start from Thursday, Jan 23.
Assignments
1.
Using Fermat’s principle,
prove Snell’s Law (law of refraction).
Read the section on
reflection and refraction in the book chapter EM theory (section 1.9.1).
Labs
While doing the lab, do not provide answers by
trial and error. For every wrong answer you provide, your lab marks will be
deducted by Labvolt.
So, think before you ink. Even if you get 100% in the post-lab quiz, it
does not ensure that you got full lab marks. The exact weight of the post-lab
quiz and that of lab performance is already fixed by Labvolt,
which cannot be changed.
The Lab1 is about familiarization with the
kit. Please go through the following material before doing the lab:
http://power.mcmaster.ca/spencer/facet/Fiber_Optic_Student_Workbook.pdf
If you miss the lab, you may not get a second
chance to do it.
If you need to
switch your lab, please contact the TA Mr. Donghan Li
(lid91@mcmaster.ca). The
TA will try to accommodate your request if there is a vacancy, but no
guarantee.
Quizzes
There
are two quizzes. The better quiz will be selected. The date of a quiz will be announced
at least one week prior to the quiz.
MSAF is not allowed if you are missing a quiz. The purpose of choosing a
better quiz is to accommodate for sickness, snow day, etc. However, if you miss
two quizzes, you could use MSAF for one of them and the weight of the quiz is
added to the final.
Quiz 2
Quiz2
will be on Thursday, Mar. 12 during the tutorial. The duration of quiz is
approximately 30 minutes. The TA will spend the first 15 minutes solving a
problem as usual and then, it is followed by the quiz.
Quiz 2 topic: Optical
fibers. focus is on dispersion in single mode fibers, Fourier transforms and
dispersion compensation.
Quiz 2 format: You need to solve a problem or two similar to
what is covered during tutorials.
Study
Material: Lecture notes,
text book sections, worked examples in the text book and tutorials
Rules: Use a pen. If
you write using pencil, no remarking. Please bring a paper and a calculator to
do the quiz.
