DESCRIPTION The Fiber Optics and Lasers module teaches students about basicconcepts of these technologies. Students perform experiments toobserve these phenomena, and explore career opportunities inthese continuously growing fields. DETAILS This module offers a close-up look at how glass fibers as thin as hairs carry information and sound to anywhere in the world, in a matter of seconds. It also explores the development and applications of laser technology, which is used in surgical tools, bar code scanners, and motion sensors, as well as communications systems. First, students learn the principles and terminology of fiber optics and laser technologies. They also learn about radio, voice, data and Morse code transmission, and the characteristics of different types of light. Other topics of discussion and exploration include reflection and refraction, the frequency spectrum, attenuation and bending loss, fiber drawing and manufacturing. Students observe these principles at work and reinforce their knowledge through several experiments. In one project, students learn how to use fiber optic cable to generate communication techniques. As students develop more knowledge and skills, they are able to design their own experiments related to fiber optics technology.
