Abstract
A highly efficient optical burst transmitter is provided. An embodiment is an optical burst transmitter including a control circuit configured to output a data signal and a burst control signal and a semiconductor optical amplifier configured to output an optical data signal modulated using the data signal as an optical burst data signal controlled using the burst control signal, the optical burst transmitter including: an electric line configured to connect the control circuit and the semiconductor optical amplifier and transmit the burst control signal; and an impedance matching circuit configured to impedance-match a characteristic impedance of the electric line and the semiconductor optical amplifier with each other.
