Generation of flat broadband chaotic signal is demonstrated experimentally with a semiconductor laser loop, which consists of three laser diodes mainly. The output of each laser diode is injected into its neighbor diode as a loop. The injection light strength is controlled with erbium-dropped optical fiber amplifier or attenuator which is inserted between the diodes, and the detuning is adjusted by changing the temperature of the laser diode. Limited by the bandwidth of the laser diode, the bandwidth of the flat broadband chaotic signal is broader than 27 GHz or even more, and the fluctuation of the spectrum cure is less than 5 dB.
