For the School Of Scientific Thought (SST) program, PhoSoc Outreach team members Eric J. Stanton, Victoria Rosborough and Takako Hirokawa developed a hands-on activity for high school students, in which students made their own laser-communications transceiver.
The short activity allows the students to optically transmit music (from a smartphone, for example) via an LED or Laser, and receive it to listen on headphones. Students can compare the use of an LED/laser and optical fiber/free-space by simply listening to the received audio quality!

This activity is based on Simon Field’s plans at sci-toys.com: Simple laser communicator
SST was made possible by Wendy Ibsen at the Center for Science and Engineering Partnerships and AIM-Photonics.
