Outline:
Optical electronics is the fusion of optical technology, quantum electronics engineering, and electronics engineering. It has helped diversify and improve the performance of electronic engineering functions and has a wide range of content. Optical devices make up the core devices within this, and this technology has advanced significantly. In this course, the first half will focus on the basics and theory of optical devices. The second half will explain various optical devices used for optical information transmission, optical recording, and image information technology using the latest information.
Style:
Students who miss 1/3 or more of classes will not be eligible for a passing grade
The overall evaluation will be based 80% on periodic exams and 20% on report assignments. The minimum score for a pass will be 60%. The periodic exam will assess students' level of understanding of the class content. There will be only one exercise and it will assess whether Course Objective 2) has been achieved.
Notice:
This course's content will amount to 90 hours of study in total. These hours include the learning time guaranteed in classes and the standard self-study time required for pre-study / review, and completing assignment reports. It is recommended that students have mastered subjects related to electronic properties.
Students who miss 1/3 or more of classes will not be eligible for a passing grade.
