%X The high frequency message filtering characteristics of the semiconductor laser which act as a receiver are numerically simulated in a scheme of closed-loop optical chaos communications system. Both transmitter and receiver are realized bysemiconductor lasers subject to strong optical injection. We examined the filtering properties of semiconductor laser with modulation message with different frequencies and amplitudes. The results demonstrate that the filtering effectiveness of the semiconductor laser receiver is higher for low frequency message and decreases as the message frequency approaches the relaxation oscillation frequency of the semiconductor laser. The quality of message recovery in such systems is shown to depend not only on the synchronization quality but also on the difference in amplitude of the message in the transmitter and receiver outputs.
