Optoelectronics (12/2) W.-Y. Choi
Lect. 1: Introduction
What is light?
Visible light, Wavelength: 400-700 nmFrequency: 430 – 750 THzPhoton energies: 1.65 - 3.1 eV
Why do we see only what we see?
- Wikipedia: EM radiation of a wavelength visible to human eye

Lect. 1: Introduction
● Presentation
Each student is expected to choose a topic related to optoelectronics and make a in-class presentation in English. The presentation will be graded based on following:relevance to the selected topic to the course, the knowledge of the student on the topicand presentation skills.
● Lunch Meeting:
Students are encouraged to participate in lunch meetings with fellow students andprofessor. Lunch meetings will be held on Wed. from 11:50 - 12:20 in my office. Sign-upsheets will be available. We can have free conversation on the course, future careerplans, etc. Sandwiches and drinks will be provided. A sign-up sheet will be available nextMonday.
