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.
Students can acquire the fundamental skills of wide ranges of the optical fiber communication technologies as follows;
(1) To learn various kinds of optical fiber communication systems
(2) To acquire the knowledges of optical waveguiding
(3) To analize the bandwidth limitation of optical fibers
(4) To aquire the knowledges of optical signal modulation / demodulation, and calculate bit error rate
(5) To utilize the concept of mode control on semiconductor lasers
(6) To design the performance limitation of semiconductor lasers
(7) To explain the basic principle of optical sensing and its application to measurement
(8) To explain the characteristics of optical devices used in optical sensing and measurement technologies
