STEM1000 Communicating with Light: An Introduction to Optical Communication Technology 光通訊技術初探

This course introduces the physical principles and technology of transmitting information (such as "voice“) using electromagnetic waves (light). Through lab projects, students will explore (1) how light can be modulated to encode information and (2) how multiple information signals can be transmitted simultaneously through frequency-division multiplexing (i.e., through use of different wavelengths of light). Students will also learn how to measure the quality of transmission by performing signals comparison with the aid of Statistics and Calculus and understand the basic concepts and applications of electromagnetic waves, quantum physics and solid-state electronics.

本課程介紹利用電磁波(光)傳遞信息(如「語音」)背後的物理原理和技術。透過實驗,學生將探索(1)如何將信息編碼入傳播的光線中,以及(2)如何利用不同頻率(即通過使用不同波長的光)同時傳輸多種信息信號。學生還可學習如何通過統計和微積分進行信號比較來測量傳輸質量,並可了解電磁波,量子物理學和固體電子學的基本概念和應用。
