摘要
This invention discloses the following. Two modulation currents are injected into different electrodes of a semiconductor laser having a plurality of electrodes. The relationship between the phases of the two modulation currents is so adjusted that an output waveform is not distorted especially when a modulation frequency is low. Polarization modulation is applied as the modulation form.
