In the systems considered in this work, the intensity of an optical source is modulated to transmit signals. This chapter investigates which type of modulation is most suitable for use in low-power systems, operating at data rates in the order of 0–10 Mbps. Digital transmission is chosen because digital signals allow for source coding (data compression), channel coding (error detection/correction) and easy multiplexing of multiple information streams. Analogue processing would be much more complicated.
