In this contribution, the effects of two key internal parameters, i.e. the linewidth-enhancement factor [Formula: see text] and gain nonlinearity [Formula: see text], on time-delay signatures (TDS) concealment of two mutually-coupled semiconductor lasers (MCSLs) are numerically investigated. In particular, the influences of [Formula: see text] and [Formula: see text] on the TDS concealment are compared and discussed systematically by setting different values of frequency detuning [Formula: see text] and injection strength [Formula: see text]. The results show that the TDS can be better suppressed with high [Formula: see text] or lower [Formula: see text] in the MCSLs. Two sets of desired optical chaos with TDS being strongly suppressed can be generated simultaneously in a wide injection parameter plane provided that [Formula: see text] and [Formula: see text] are properly chosen, indicating that optimizing TDS suppression through controlling internal parameters can be generalized to any delayed-coupled laser systems.

We report the investigation of the time delay signature in chaotic semiconductor subject to delayed filtered optical feedback, of which a Fabry-Pérot interferometer type of filter is placed in the external cavity. The numerical results show that the suppression of time delay is dependent on the spectral width of the filter and its detuning from the solitary laser frequency. Such laser system will be helpful to acquire high quality chaotic signals.
