Course Description: Lightwave communication has
emerged as the undisputed
transmission method of choice in almost all areas of
telecommunication, mainly because it offers unrivaled
transmission capacity at low cost. Starting with the design
of photonic devices for lightwave
generation, modulation,
amplification and detection and optical fibers for lightwave
transmission, this course will mainly focus on the design of
light wave communication systems and networks.

Policy
reminders:
The Faculty of Engineering is
concerned with ensuring an environment that is free of all adverse
discrimination. If there is a problem,
that cannot be resolved by discussion among the persons concerned, individuals are reminded that they should
contact the Department Chair, the Sexual Harassment Officer or the Human Rights
Consultant, as soon as possible.
Students are reminded that they
should read and comply with the Statement on Academic Ethics and the Senate
Resolutions on Academic Dishonesty as found in the Senate Policy Statements
distributed at registration and available in the Senate Office.
Academic dishonesty consists of misrepresentation by deception or by other fraudulent means and can result in serious consequences, e.g. the grade of zero on an assignment, loss of credit with a notation on the transcript (notation reads: "Grade of F assigned for academic dishonesty"), and/or suspension or expulsion from the university. It is your responsibility to understand what constitutes academic dishonesty. For information on the various kinds of academic dishonesty please refer to the Academic Integrity Policy, specifically Appendix 3, located athttp://www.mcmaster.ca/senate/academic/ac_integrity.htm The following illustrates only three forms of academic dishonesty: 1 Plagiarism, e.g. the submission of work that is not one's own or for which other credit has been obtained. For example, lab assignments should be done by each student separately.
2 Improper collaboration in group work.
3 Copying or using unauthorized aids in tests and examinations.
