Third and fourth grade classes
Opening movie of the first photonics class (2020)
The term "photonics" originated in the 1960s and 1970s with the rapid development of optical fiber technology and semiconductor laser technology based on quantum mechanics, and the idea of developing technologies that fuse photonics and semiconductor electronics. Photonics has played a central role in the development of optical communication systems in the past, and will continue to play an essential role in the development of next-generation core technologies for communication and information processing, such as optical interconnects, optical integrated circuits, and optical quantum information processing. In this sense, photonics is a discipline that, despite its relatively ancient origins in electromagnetics, can be described as a work in progress whose engineering applications and value are still changing from moment to moment.
Since the foundation of photonics is electromagnetism, this lecture begins with Maxwell's equations and first covers the basic behavior of light. Next, we will learn about the propagation of light in optical fibers and artificial waveguides, which form the basis of today's optical communications. In addition, state-of-the-art research topics such as light propagation in nanostructures, which has been made possible by advances in nanotechnology, will also be introduced. Finally, the physics of light and semiconductor devices, another pillar of photonics, will be studied with a focus on semiconductor lasers.
The lectures are designed to be as intuitive and convincing as possible by interweaving physics such as electromagnetism and semiconductor properties with engineering topics. However, in order to promote true understanding, it is necessary for students to work on their own, and therefore, mathematical formulas that support intuitive interpretation will be checked in reports.
Message to students:.
To "understand" physics, it is necessary to be able to intuitively perceive the phenomena and to be able to describe the phenomena as mathematical expressions that can be easily handled by modeling them, and neither of these must be lacking. If students only read reference books and solve exercises by themselves, they tend to get caught up in mathematical formulas, and it is not easy to smoothly understand the phenomena. The class will pay attention to the explanation of how to intuitively interpret the phenomena (in addition to the description by mathematical formulas). Therefore, please understand that the most efficient way to learn is to attend the class. Please review Physics D of the first year well.
Special Lecture on Electrical and Computer Engineering
Lectures on recent topics in various fields of electrical and information engineering will be given by invited lecturers from inside and outside Japan.
Electrical and Computer Engineering Laboratory 2
Learn about the basics of laser technology
Message to students:.
Lasers are used in a variety of applications. Quantum cryptography is also expected to become the next generation of secure communication. Students will learn about these technologies through hands-on experience.
Special Exercises in Electrical and Computer Engineering
The purpose of this program is for students to experience the actual front lines of industry through group tours of several Japanese companies, mainly manufacturing companies, and to reaffirm their awareness of working in society and their career aspirations through interaction with engineers and researchers in the field. The purpose of the tour is to reaffirm the awareness of working in society and hopes for a career path through interaction with engineers and researchers on the front lines of industry. The purpose of this program is completely different from a company tour for job hunting. It is very meaningful as an exchange with graduates, classmates, and class teachers, and we hope that you will actively participate. This course is usually offered in mid-February of the third year, but due to the grading system, students are required to take the course when they advance to the fourth year in order to obtain credits. For more information, please contact the Assistant Director of Academic Guidance.
Attention! To all bachelor students
Part-time job wanted!
We are holding a lab information session for students who will be assigned in 2024. Please feel free to come and go in and out of the open laboratory. (Individual information sessions are also available at any time.
