Free-space communication in the mid-IR domain has many potential applications, but security is still challenging. Here, the authors use chaos synchronization in a QCL-based free-space link as a way to increase privacy of such transmissions.

In this paper we investigate the generation, manipulation and invariance properties of spatially unpolarized light in the context of classical optics. We generate spatially randomly polarized light by exploiting the optical activity of a so-called Co

We demonstrate wavelength-wavelength correlations of classical broad-band amplified spontaneous emission (ASE) photons emitted by an erbium-doped fiber amplifier (EDFA) in a wavelength regime around 1530 nm. We then apply these classical correlated p

Mid-infrared free-space optical communication has a large potential for high speed communication due to its immunity to electromagnetic interference. However, data security against eavesdroppers is among the obstacles for private free-space communica

We report on the first experimental chaos synchronization in mid-infrared quantum cascade lasers and subsequently perform private free-space transmission at a bit-rate of 0.5 Mbits/s. The quality of the privacy is assessed with eye diagrams, both at

Temperature dependent suppression of intensity noise below thermal fluctuations g (2) (0) < 2 in incoherent quantum dot superluminescent diodes (QDSLDs) has been observed by Blazek et al. in 2011 [1] . First-order temporal correlation properties of Q

In this paper, we investigate depolarization properties of a quartz double-wedge Cornu depolarizer with respect to the generation of spatially unpolarized light in terms of on-average randomly occupied states on the Poincaré sphere. Spatially resolv
