On completion of this course, students should be able to:

1. define and explain the propagation of light in conducting and non-conducting media;
2. define and explain the physics governing laser behaviour and light matter interaction;
3. apply wave optics and diffraction theory to a range of problems;
4. apply the principles of atomic physics to materials used in optics and photonics;
5. calculate the properties of various lasers and the propagation of laser beams;
6. calculate properties of and design modern optical fibres and photonic crystals;
7. use the tools, methodologies, language and conventions of physics to test and communicate ideas and explanations;
8. integrate several components of the course in the context of a new situation (unique to postgraduate coursework).

Description of Assessment:

While this course is offered concurrently to undergraduate students, all postgraduate students are expected to perform at a higher level both qualitatively and quantitatively. To facilitate this, postgraduate students are required to address additional content in the assignments/tests and the examination within the same timeframe as undergraduate students.

Projects, Assignments and Tests: (40% of total course grade)

The standard assessment consists of 2 projects/assignments and 2 tests. This may be varied by negotiation with students at the start of the semester. This combination of projects, tests and summative assignments is used during the semester to address understanding of and ability to use the course material and to provide students with a benchmark for their progress in the course.

Postgraduate students are required to complete additional assessment tasks within each project/assignment to demonstrate additional understanding of the course material, in particular the ability to integrate different course components in a novel context.

Written Examination: (60% of total course grade)

One 3 hour exam is used to assess the understanding of and ability to use the material. Within the 3 hours, postgraduate students are required to answer additional question(s) in comparison to the undergraduate exam.

Final result

For each student, the result is determined by combining the components Projects/Assignments, Tests and Written Exam using each of the possible weightings:

-         20%(Projects/Assignments) + 20%(Tests) + 60%(Exam)

-         20%(Projects/Assignments) + 5%(Tests) + 75%(Exam)

-         5%(Projects/Assignments) + 20%(Tests) + 75%(Exam)

If an extension is not applied for, or not granted then a penalty for late submission will apply.  A penalty of 10% of the value of the assignment for each calendar day that the assignment is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days late or more without an approved extension can only receive a maximum of 50% of the marks available for that assignment.
