EE 232 ¡V Lightwave Devices

Project Term Paper

Scope

The purpose of the term paper is to provide the students an opportunity to perform device designs from scratch, based on the fundamental material taught in the class, most of which theoretical.

Students will work in teams of two or three. Students will start the project by first examining the requirements of a chosen application, then proceed with a set of design, and finally calculate the device performance based on the theories taught in class and in technical publications. Students are expected to discuss some or all of the following aspects.

• tolerance of design parameter(s)
• relative impact of various design parameters on device performance
• device yield
• impact of design variation on yield

Presentation

Each project team will present their findings in a 40-minute session, including a 10-minute presentation by each team member and a 10-minute question and answer session. A hardcopy and softcopy of the viewgraphs are required before the class presentation. This portion represents 30% of the course grade.

Term Paper

There is no page limitation. However, each paper must follow the standard technical journal format, including abstract, introduction (or motivation), application requirements, device design, modeling, calculated results, discussions, and references. The reference section should be formatted using IEEE technical journal format, including the full list of authors and titles of the papers. This portion represents 30% of the course grade.

Evaluation

The evaluation will be based on thoroughness, depth, clarity, design complexity, and originality and breadth of the discussions.

Suggested Topics

Students can pick a device and an application either from the list below or totally on their own. The topic needs to be approved by the instructor either verbally during office hours (highly recommended) or by submitting an abstract.
