Infra red devices are used for communication over short distances. There are some notes on this site about using infra-red in word format and an article on making easy remote control.
There are some excellent notes on using infra-red from the Zetex website. Zetex are a transistor and IC manufacturer based in Oldham near Manchester.
There are some good notes from Vishay Telefunken on the physics of infra red emitters.
