STEM1000 Communicating with Light: An Introduction to Optical Communication Technology 光通讯技术初探

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.

本课程介绍利用电磁波(光)传递信息(如「语音」)背后的物理原理和技术。透过实验,学生将探索(1)如何将信息编码入传播的光线中,以及(2)如何利用不同频率(即通过使用不同波长的光)同时传输多种信息信号。学生还可学习如何通过统计和微积分进行信号比较来测量传输质量,并可了解电磁波,量子物理学和固体电子学的基本概念和应用。
