Laboratory #3 Introduction to Photonics Fall 2007 1 Description: This week’s lab will introduce you to the area of photonics. Photonics is a sub-discipline of Electrical Engineering that combines the fields of optics, optoelectronics, and electronics. We will be exploring the field of photonics by performing a few experiments that highlight different applications of photonics. First we will learn about optical fiber by measuring the numerical aperture of a communications grade, glass optical fiber. After that we will look at the basic parts making up a liquid crystal display on your laptop or cell-phone screen. Finally, we will evaluate the beam divergence of several different light sources that are used in various photonics applications. Beyond introducing the field of photonics, this lab will give you an opportunity to take and graph data, interpret the measured results from an experiment, and observe/describe changes in an experimental result. These skills are important in a wide variety of laboratory settings including many of the lab courses you will take throughout your engineering degree program. This lab will allow the student to experiment with optical systems that utilize lasers. For reasons of safety, it is important that each student follows all directions given by the laboratory personnel. Requirements: To help with data analysis, you will need a scientific calculator (i.e. one capable of calculating sin ± ). All other equipment required for your introduction to photonics will be provided in the laboratory. As always, reading this guide prior to lab is helpful along with your enthusiasm and patience. 1.0 Introduction Photonics is a sub-discipline of Electrical Engineering. Photonics is primarily involved with the generation, manipulation and detection of light. Popular examples of photonic systems include DVD players, CD ROM drives, modern camcorders, flat screen TVs, and fiber optic telecommunications systems. While these applications represent the most successful commercial application of photonics, there are a wide variety of applications that show significant promise for the future. With its basis in optics, photonics has a long history dating back to early optical system designers like Galileo and Newton who first began exploring the potential of using optics for gathering information about the world around them. With the invention of semiconductor devices in the 1950’s and lasers in the 1960’s, photonics began to develop into a major engineering discipline. Perhaps the first, significant, photonic system was synthetic aperture radar (SAR) that used lasers and optics to significantly enhance the resolution of airborne radar systems. From these rather specialized beginnings, photonics has grown into a multi-billion dollar industry that currently employees in excess of 100 thousand engineers worldwide. With future application ranging from ultra-high density optical storage to micro-controlled lasers used to perform heart surgery, photonics promises to be a growing market well into the 21st century.
