Abstract
A semiconductor laser modulation signal is generated for modulating a semiconductor laser. The semiconductor laser is driven based on the semiconductor laser modulation signal. An output impedance of a semiconductor laser modulation signal generating unit and an input impedance of a semiconductor laser driving unit are corrected. The semiconductor laser modulation signal is transmitted as a low amplitude differential signal, from the semiconductor laser modulation signal generating unit to the semiconductor laser driving unit.
