Course Outline:

Description:

This is an introductory-level course in the field of solid-state optoelectronics. It includes an introduction to the microscopic properties of solids such as bulk metals, insulators, semiconductors, polymers, glass and semiconductor heterostructures, as well as their linear and nonlinear optical response. It also contains a discussion of basic operation of principles of opto-electronic devices such as lasers, light modulators and detectors.

A necessary prerequisite is a good understanding of basic electromagnetic theory (including Maxwell’s equations and the mathematics of Fourier transformations) and quantum mechanics (including the physics of the hydrogen atom and perturbation theory).

Some of the topics of this course will be covered in detail (for example, the linear optical response of solids, simple optical properties of phonons and the physics of quantum wells), whereas other topics will only be covered in the form of general overviews (for example electro-optical properties of semiconductors and nonlinear optical effects).

 No advanced mathematical techniques, such as second quantization, will be used.

 There are two major goals of this course. First, the course should present basic facts about optical properties of solids based on their microscopic structure. Second, the student should be enabled to understand various optical and opto-electronic phenomena used in devices on the basis of the few microscopic aspects presented in this course.

 Homework:

  • Weekly homework assignments with a few problems will be handed out each week. The homework is due one week later.

 Exams:

  • Closed book in-class MIDTERM EXAM.

  •  Closed book in-class FINAL Exam.

 Grades:

  • The grades will be based 20% on the homework, 40% on the midterm and 40% on the final exam.
