The properties of the isochronal chaos synchronization (ICS) in two multiple time-delayed coupling (MTDC) semiconductor lasers (SLs) subject to identical chaotic injections from a third laser are studied systematically. We numerically investigate the influences of the MTDCs and the driving injections, the mismatch robustness and detuning tolerance, the chaos pass filtering effects, and the multichannel communication performance. The numerical simulations demonstrate that stable ICS can be readily achieved in the present system as long as the driving injections are properly strong, and it is not restricted by the coupling delays, which is more advanced than that of MTDCSLs with self-feedback where the ICS is closely related to the relationship between the coupling delays and the feedback delays. Moreover, the ICS is robust to relatively large mismatch of the pumping current and device parameters and is robust to frequency detuning up to tens of gigahertz. When the external modulation technique is adopted, striking chaos pass filtering effects that are not limited by the relaxation oscillation frequency are observed in each coupling path, which enables us to transmit 2n messages over n coupling paths simultaneously. The proposed scheme provides a potential way for the implement of optical chaos communication networks.
