We numerically demonstrate that stable isochronal chaos synchronization (ICS) can be achieved by adding individual self-feedback or external driving to two multiple time-delayed coupling semiconductor lasers (MTDCSLs). The properties of the ICS, such as the influences of the coupling parameters, the mismatch robustness, the chaos pass filtering effects, and the communication performance in these two MTDCSL configurations, are comparatively studied. Moreover, we show that the proposed schemes afford multichannel chaos-based communication with the chaos modulation technique, which provides a potential method for the realization of chaos communication networks.
