Special Issue Information

Dear Colleagues,

The activity in the field of nanostructured materials and systems for advanced optical applications is amazing in terms of new science, new technologies, and new products covering a very broad spectrum of applications. The application of these structures allows to successfully face socio-economic challenges in many fields—from energy to efficient photons management, from environmental protection to novel integrated communication systems, from structural monitoring to quantum technologies and to healthcare applications. Nanostructured systems for advanced optical application are the focus of this Special Issue. The general idea is to collect impressive papers devoted to the physical, chemical, and hybrid fabrication techniques; to the design of innovative systems; to the modeling and simulation of the physical and chemical mechanisms and properties; to the theory behind nanostructured optical systems. Concerning spectroscopic, optical, morphological, and structural assessment, we expect scientific papers employing diagnostic techniques covering photoluminescence, time resolved spectroscopy, Raman, AFM, TEM, SEM, XPS, Neutron scattering, synchrotron radiation based technologies, thermodynamic analysis and more. Emphasis is expected for new physical and chemical properties. Technical articles looking at novel diagnostic, design and fabrication of components and devices are also welcome. The aim of this Special Issue is to gather experiences of leading scientists, but also to be a guide for people who needs to confront with non-conventional and emerging routes for the development of nanostructured materials and systems for advanced optical applications. From this point of view, we believe that the Special Issue will provide the presentation of technological advances and the latest research on the state-of-the-art in innovative processing and device applications of new materials to meet the challenges of sustainable energy and optical nanotechnologies.

Low-Threshold Coherent Emission at 1.5 µm from Fully Er3+ Doped Monolithic 1D Dielectric Microcavity Fabricated Using Radio Frequency Sputtering
Ceramics 2019, 2(1), 74-85; https://doi.org/10.3390/ceramics2010007 - 21 Jan 2019

Low threshold coherent emission at 1.5 µm is achieved using Er3+-doped dielectric 1D microcavities fabricated with a Radio Frequency-sputtering technique. The microcavities are composed of a half-wavelength Er3+-doped SiO2 active layer inserted between two Bragg reflectors consisting of ten, five, and seven pairs of SiO2/TiO2 layers, also doped with Er3+ ions. The morphology of the structure is inspected using scanning electron microscopy. Transmission measurements show the third and first order cavity resonance at 530 nm and 1.5 µm, respectively. The photoluminescence measurements are obtained using the optical excitation at the third order cavity resonance using a 514.5 nm Ar+ laser or Xe excitation lamp at 514.5 nm, with an excitation angle of 30°. The full width at half maximum of the emission peak at 1535 nm decreased with the pump power until the spectral resolution of the detection system was 2.7 nm. Moreover, the emission intensity presents a non-linear behavior with the pump power and a threshold at about 4 µW. Full article

In this review, we report on the design, fabrication, and characterization of photonic crystal arrays, made of two and three coupled nanocavities. The properties of the cavity modes depend directly on the shape of the nanocavities and on their geometrical arrangement. A non-negligible role is also played by the possible disorder because of the fabrication processes. The experimental results on the spatial distribution of the cavity modes and their physical characteristics, like polarization and parity, are described and compared with the numerical simulations. Moreover, an innovative approach to deterministically couple the single emitters to the cavity modes is described. The possibility to image the mode spatial distribution, in single and coupled nanocavities, combined with the control of the emitter spatial position allows for a deterministic approach for the study of cavity quantum electrodynamics phenomena and for the development of new photonic-based applications.

Nanocrystalline La1−xNdxFeO3 powders with different concentrations of Nd3+ have been synthesized using a modified Pechini method. Their structures were studied by X-ray powder diffraction (XRD). Furthermore, La1−xNdxFeO3 nanoceramics were prepared using a high pressure sintering technique. The luminescence spectra of the powders were investigated as a function of concentration of active dopant to check the possible energy transfers observed due to Nd3+ concentration changes. The electrical and magnetic properties of the powders and ceramics were investigated to determine the effect of Nd3+ doping on the dielectric permittivity and magnetization in the wide frequency range.

Improving optical fiber amplifiers requires the elaboration and use of new materials and new compositions. In this sense, we prepared erbium-doped optical fiber samples that were co-doped with magnesium or lanthanum by gradual-time solution doping. Doping concentrations and thermal processes induce the formation of nanoparticles. The effect of lanthanum and magnesium contents on the width of the spontaneous emission of the 4 I 13 / 2 level of Er 3 + was characterized in the nanoparticle-rich fiber samples. For that purpose, the width was characterized by the effective linewidth and the full-width at half-maximum (FWHM). The results indicate the robustness of the effective linewidth to strong variations in the intensity profiles of the 4 I 13 / 2 spontaneous emission. Increasing the doping concentrations of both magnesium and lanthanum increases the FWHM and the effective linewidth, along with optical losses. Results show that the fabrication of nanoparticle-rich optical fibers through lanthanum or magnesium doping induces an FHWM broadening of 54% and 64%, respectively, or an effective linewidth broadening of 59% (for both elements) while maintaining a transparency that is compatible with fiber laser and amplifier applications.

Weyl semimetals can be described as the three-dimensional analogue of graphene, showing linear dispersion around nodes (Weyl points). Tantalum arsenide is among the most studied Weyl semimetals. It has been demonstrated that TaAs has a very high value of the real part of the complex refractive index in the infrared region. In this work we show one-dimensional photonic crystals alternating TaAs with SiO2 or TiO2 and a microcavity where a layer of TaAs is embedded between two SiO2-TiO2 multilayers. Full article
