Nanostructured devices and materials offer a way to overcome the conventional light absorption limits.
Novel optical spectrum splitting and photon-recycling schemes boost the efficiency of optical energy-conversion platforms. Furthermore, optical design concepts are rapidly expanding into the infrared energy band, offering new approaches to harvest waste heat and to reduce the thermal emission losses in solar-thermal and solar water desalination platforms.
Broadband engineering of the emission properties of optical materials and devices also paves the way to achieving noncontact radiative cooling of solar cells, electronic circuitries, buildings, and vehicles.

Numerical study on dynamics-dependent synchronization in mutually-coupled lasers with asymmetric feedback. Keywords: synchronization , chaos , nonlinear dynamics , semiconductor lasers. Article overview. References Theoretically, the chaotic waves are generated iteratively by chaotic maps, and practically, by electronic circuits or lasers. Both single-user and multiple-user systems are covered.
The focus is on likelihood-based decoding of messages, essentially estimation of binary-valued parameters and efficiency of the system is in terms of the probability of bit decoding error.
The emphasis is on exact theoretical results for bit error rate, their structured approximations and engineering interpretations. Design issues, optimality of performance, interference and fading are other topics considered. The statistical aspects of chaotic synchronization are involved in the modelling of optical systems. Empirical illustrations from an experimental laser-based system are presented. The overall aim is to show the use of statistical methodology in unifying and advancing the area. Source Statist.
