“…Rigorous accountings of light generation in arbitrary homogeneous media typically begin with incorporating source terms into Maxwell's equations. Solutions are given in terms of dyadic Green's functions, in which the net electric field in the exit medium is written as a volume integral [52][53][54]. We question, however, whether this approach is appropriate for luminescence because an integral over field amplitudes is fundamentally a coherent superposition, analogous to casting Eq.…”

Complete polarimeters deliver the full polarization transfer matrix of a medium that relates input polarization states to output polarization states. In order to interpret the Mueller matrix of a luminescent medium at the emission frequency, accountings are required for polarization transformations of the medium at the excitation frequency, the light scattering event, and the polarization transformations at the emission frequency. A general framework for this kind of analysis is presented herein. The fluorescence Mueller matrix is expressed as a product of Mueller matrices of the medium at the excitation and emission frequencies and a scattering matrix, integrated over path length. The Stokes vector for the incident light, evolving according to the Mueller matrix of the medium at the excitation frequency, is multiplied by the scattering matrix to give a Stokes vector of the emitted light along the propagation direction. The scattering matrix is derived from an incoherent orientation ensemble average over a phenomenological scattering tensor that embodies intrinsic molecular scattering proprieties, and dynamical processes that occur during the excited state. The general framework is evaluated for three anisotropic materials carrying luminescent dye molecules including the following: a chiral fluid, a stretched polymer film, and a chiral, biaxial crystal. In the latter case, the most complex, the Mueller matrix was collected in conoscopic illumination and the fluorescence Mueller matrix, mapped in k-space, was fully simulated by the strategy outlined above. Luminescence spectroscopy has typically stood apart from the developments in polarimetry of the past two generations. This need not be indefinite.

A new selenide with a diamond-like structure, Li MnSnSe , was synthesized for the first time by using a conventional high-temperature solid-state reaction method. Li MnSnSe crystallizes in the space group Pmn2 (no. 31) of the orthorhombic system. Its three-dimensional framework is constructed by corner-sharing LiSe , MnSe , and SnSe tetrahedra. The title compound has been discovered to have both type I phase-matchable behavior and to exhibit moderate powder second-harmonic generation intensity, about 0.5 times that of commercial AgGaS in the particle size of 200-250 μm at a laser radiation of 2.09 μm. In addition, Li MnSnSe exhibits congruent melting behavior, which makes the bulk single-crystal growth by the Bridgman-Stockbarger method possible. The temperature-dependent susceptibility measurement indicates an antiferromagnetic interaction with a Néel temperature (T ) of 8.6 K for this compound.

This Element introduces the exotic wave phenomena arising from the extremely small optical refractive index, and sheds light on the underlying mechanisms, with a primary focus on the basic concepts and fundamental wave physics. The authors reveal the exciting applications of ENZ metamaterials, which have profound impacts over a wide range of fields of science and technology. The sections are organized as follows: in Section 2, the authors demonstrate the extraordinary wave properties in ENZ metamaterials, analyzing the unique wave dynamics and the resulting effects. Section 3 is dedicated to introducing various realization methods of the ENZ metamaterials with periodic and non-periodic styles. The applications of ENZ metamaterials are discussed in Sections 4 and 5, from the perspectives of microwave engineering, optics, and quantum physics. The authors close in Section 6 by presenting an outlook on the development of ENZ metamaterials and discussing the key challenges addressed in future works.
