Homework
There will be four bi-weekly homework assignments covering the above topics. The homework
is due two weeks after it is handed out. No late homework will be accepted.
Studying in groups is encouraged but homework must be completed independently reflecting a
student's individual effort.

Laboratory
There will be four bi-weekly labs covering: fiber optics, DFB laser, erbium doped fiber
amplifier, and high-speed optical receiver. Each lab will be approximately 3 hours long. The lab
report is due to the TA two weeks after each lab (except for Lab 4, it is due on last day of class).
Exams
Midterm: 05/03/2005
Final: 06/09/2005, 8 - 11 am
All exams are open book. Make-up exams are possible only with documentation of illness or
personal emergency.

Letter grade (4 units) is required.
Any complaints regarding exam grades must be made directly to the instructor within two
business days after the graded exams are returned; complaints regarding lab report or homework
grades must be made directly to the TA within two business days after the graded papers are
returned. A letter must be attached to your re-grading request stating clearly which question to
re-grade, and reasons why you deserve more points. The instructor and/or TA will re-grade the
requested questions truly. Note that if you deserve lower points than you have already been
given, some points will be deducted from your grand total. It is recommended that you be very
sure of your request for re-grading.
Academic dishonesty will not be tolerated. This includes copying another student’s homework,
allowing another student to copy your homework, cheating on exams, and altering graded papers.
In accordance with UCR policy, every incident of academic dishonesty must be reported to the
college dean.

Course Learning Objectives
The following list gives some specific learning objectives for this course, identified by the
instructor as important concepts and/or skills to learn.
1. Understand and be able to explain the physical principle for how an optical fiber guides
light.
2. Be able to estimate the limitations on transmission speed and/or distance caused by fiber
dispersion.
3. Understand and be able to explain the advantages, and limiting characteristics of
semiconductor lasers as used in fiber-optic communications.
4. Understand and be able to explain the operating principles of semiconductor
photodetectors, and the main noise sources that corrupt the detection process.
5. Be able to estimate the receiver sensitivity for P-I-N, APD, and optically pre-amplified
receivers.
6. Understand and be able to explain the operating principle, advantages, and limitations of
erbium doped fiber amplifiers.
