Optoelectronics (14/2) 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



Why do we see only what we see?

-Light has been the most abundant EM waves for long time!



- Why study light in EEE? Many applications

LED: Light Emitting Diode

LEDs have much better efficiency and longer life time.Expected to replace all lighting systems, eventually




LASER: Light Amplification by Stimulated Emission Radiation

Material Processing Laser Surgery Hologram




Optical Fiber Communication

Light can travel inside fiber with very small loss Key technology for internet revolution!







Data center for cloud computing



-Why study light in EEE?

Many applications in Information TechnologyInformation Transmission: Optical Communication/InterconnectInformation Display: LCD, LED, HologramInformation Storage/Recovery: CD, DVD, HologramMedical Applications: Surgery, Imaging,
