Optoelectronics experiments for first-year engineering students

This paper describes a set of experiments in optoelectronics for first-year engineering students. This laboratory experience is comprised of five inexpensive and transportable modules that provide a hands-on introduction to optoelectronics, these modules include different types of emitters, light-emitting diode (LED) colors, optical voice link, total internal reflection and waveguiding. Designed by a senior electrical engineering student, these modules appeal to students with various learning styles. Two hundred eight-five first-year engineering students at Bucknell University and the University of San Diego (USA) have performed these experiments. Student response to the laboratories has been enthusiastic with 80% of the students rating the lab as very good or excellent overall. Further assessment of the experiments by the instructor and the students is also discussed.
