The emission and propagation of light in disordered media has always been a topic of interest in science, mainly because in nature this is the most common way of light emission and propagation. This research topic received a particular attention after the report of the first highly efficient random laser (RL) [1]. Indeed a large number of investigations discussing the fundamentals and the applications...
The emergence of long range phase coherence among random nonlinear waves is a fascinating effect that characterizes many fundamental phenomena. For instance, the condensation of classical waves [1,2] is an important example of self-organization process that generates lot of interest as a classical analogue of quantum Bose-Einstein condensation. Wave condensation is known to be characterized by the...
In optomechanical systems, co-localizing light and mechanical oscillations at the nanoscale can lead to strong interaction between photons and phonons. Such optomechanical coupling enables sensitive detection of nanoscale motion, as well as control of the motion through optical forces down to the quantum level [1]. In the vast majority of cases, the optomechanical coupling can be regarded as linear...
Optical diffraction tomography provides a powerful tool for imaging the 3-D refractive index (RI) distribution. However the method suffers from two major issues. The first one is the missing cone problem that comes from limited illumination angles. The missing cone problem can be dealt with sparsity based regularization [1]. The second problem is the nonlinear relationship between the refractive index...
Quantum technology is a fundamentally new way of harnessing Nature and it has potential for a truly revolutionary innovation and promise the next generation of products with exciting and astounding properties that will affect our lives profoundly. They will have a great influence in defence, aerospace, energy and telecommunications sectors. If this process is to continue in the future, new, quantum...
Extended-cavity quantum cascade lasers (EC-QCLs) enable mode-hope-free frequency sweeps in the mid-infrared region over ranges in excess of 100 cm−1, at speeds up to 1 THz/s and with a 100-mW optical power level. This makes them ideally suited for broadband absorption spectroscopy and for the simultaneous detection of multiple gases. On the other hand, their use for precision spectroscopy has been...
Numerical methods can be useful for the understanding of high-Q resonators, the interpretation of frequency comb formation and the tailoring of nonlinear phenomena. For specific applications like telecommunications or low phase noise microwave generation, a phase locked frequency comb or temporal pulse train is critical. Single intra-cavity dissipative temporal solitons have demonstrated to be attractive...
Control of light propagation is usually obtained by appropriately designing the optical path, that is, the refractive index of the material. Common examples are standard lenses and dielectric waveguides. Recently, a new way to tailor the wave front emerged, based on the Pancharatnam-Berry phase (PBP). The PBP is a geometric phase related to changes in the polarization state of light along its propagation...
