Course description and aims

The course provides an overview of optoelectronics, particularly optical fiber communications, and deals with both the function of related components and with system performances.
Basic architectures and designs of optical communication systems can be understood.
In addition, operating principles of optical waveguides, optical fibers, semiconductor lasers, photodetectors, and other components, can be acquired.
Students also learn properties of optical fibers and their transmission bandwidth.
Moreover, application of optical technologies to sensing and measurements is covered from the points of systems and used optical devices in this lecture.

The knowledges of optoelectronics are based on fundamentals of semiconductor materials, electromagnetic field analysis for optical fiber properties, and simulations using frequency-domain transfer functions for fiber transmission. In optical sensing and measurement technologies, on the other hand, signal processing based on time and frequency domain are utilized. It is useful to learn Class "Optoelectronics" to acquire the application of the fundamental knowledges of electrical and electronics.

Class flow

At the beginning of each class, answers of the practice in the latest class are explained. Next, contents of the class are lectured. Toward the end of the class, the time for the practice is given to students.
Before classes, the texts are uploaded on OCW-i web site. Students should download them, and read them briefly. After classes, they are requested to read the texts for understand the contents of the classes.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.


Texts, that the lecturers are made, are used. They are uploaded on OCW-i before each lecture.

Reference books, course materials, etc.

Distribute texts on OCW-i.
