Purpose of this lecture:

Japan is known to be a giant in the field of opto-electronics. The term “opto-electronics” covers wide range of scientific and technical field relating to light; e.g., optical communications, displays, light emitting diodes, laser diodes, solar cells, and optical disks. These technologies have become indispensable to modern lives. This lecture is intended to provide foreign students under the STEP program fundamental knowledge of the opto-electronics and to attract interest to this field. For Japanese students the lecture will also provide an opportunity to have communication in English with students from abroad.
