“…The in-plane orientation of YSZ grains in the waveguide is not well defined like in classical silicon substrate and then the electric-field direction of the pump is not aligned along only one crystallographic direction. Thanks to a complete material characterization of our films, [22] we considered as a first approximation that the electric field of the pump is aligned equiprobably in the [100] and [110] directions. In this case, the experimental value n Y SZ 2 becomes an effective value n Y SZ 2 which can be compared to the theory via an effective third order nonlinear susceptibility χ (3) Y SZ , defined as follow…”

“…The growth of high quality YSZ thin film is performed with an optimized Pulsed-Laser Deposition (PLD) process on sapphire (0001), described in details reference. [22] We demonstrated that the [001] growth direction of YSZ can be largely promoted with up to six in-plane grains orientations separated by 15 degrees. The characterization by X-Ray Diffraction (XRD) of the H=300 nm thick film used in this work is presented Figure 4d and 4e.…”

Nonlinear all-optical technology is an ultimate route for next generation ultra-fast signal processing of optical communication system. New nonlinear functionalities need to be implemented in photonics and complex oxides are considered as promising candidates due to their wide panel of attributes. In this context, Yttria-Stabilized Zirconia (YSZ) stands out thanks to its capability to be epitaxially grown on silicon, adapting the lattice for the crystalline oxides family of materials. We report for the first time a detailed theoretical and experimental study about the third order nonlinear susceptibility in crystalline YSZ. Via self-phase modulation induced broadening and considering the in-plane orientation of YSZ, we experimentally obtained an effective Kerr coefficient of n Y SZ 2 = 4.0 ± 2 • 10 −19 m 2 W −1 in a 8%mol. YSZ waveguide. In agreement with the theoretically predicted n Y SZ 2 = 1.3 • 10 −19 m 2 W −1 , the third order nonlinear coefficient of YSZ is comparable to the one of silicon nitride (SiN), already used in nonlinear optics. These promising results are a new step towards the implementation of functional oxides for nonlinear optical applications.

“…Yttria-stabilized zirconia (YSZ) is an extrastable wide band gap functional oxide of high mechanical, chemical and thermal stability [19][20][21][22][23][24][25][26][27][28][29][30][31]. A considerable part of its properties are related to the presence of structural oxygen vacancies, created as yttrium cations are incorporated to zirconia dioxide to stabilize its cubic phase in room temperature [32][33][34].…”

Electronic and magnetic properties of yttria-stabilized zirconia (6.7 mol% in Y2O3) doped with Er3+ ions from first-principle computations

Yttria-stabilized zirconia (YSZ) is a widely recognized ceramic of distinct electrical, mechanical and optical properties. Although YSZ is an intrinsically paramagnetic solid, it could potentially transform to a magnetic semiconductor by incorporating in its crystalline structure isolated atoms bearing unpaired valence electrons. Based on this hypothesis and motivated by the latest advances on YSZ doped with rare-earth atoms, in the current article we report on the electronic and magnetic properties of YSZ doped with Er 3? ([Xe]4f 11 6s 0 ) cations that comprise three ''unpaired'' 4f electrons in their ground state electronic configuration. Our computations, conducted on YSZ 6.7 mol% in Y 2 O 3 doped with two different Er 3? concentrations (3.2 and 6.7 mol% in Er 2 O 3 ), expose that Er 3? :YSZ is a stable antiferromagnetic semiconductor (S ¼ 3 2 per Er ?3 ) bearing a rather wide band gap of about 5 eV. All results presented and discussed in current report rely on spinpolarized density functional theory (DFT) within the spin resolved generalized gradient approximation (SGGA) for the pure Perdew, Burke and Ernzerhof exchange-correlation functional (PBE) and hybrid version widely referred as PBE0. According to our knowledge, this is the first time that the magnetic properties of Er 3? : YSZ materials are reported for any Er ?3 concentration.

by many emerging applications such as curved or bendable IR sensors. [3] When mechanical flexibility is required, polymers, such as polyethylene terephthalate and polyethylene naphthalate, are used in the visible region, but cannot be extended to the IR as they have several vibrational absorption fingerprints. There exist polymers, including parylene C, polydimethylsiloxane, polyimide, that are more transparent in the IR and have been studied in literature. [4] However, ultraviolet lithography is not always easy on such materials due to their sensitivity to chemicals. In addition, high-resolution electron beam lithography on these polymeric substrates is restricted by their limited thermal and radiation tolerance and nonplanar nature. Alternative methods like nano-stencil lithography and self assembly techniques could be employed to fabricate sub-micrometer features on these polymer substrates. [4] Besides the difficulty of finding an appropriate lithography method for patterning, the transmission spectra of these IR polymer substrates show still many vibrational fingerprints between 2 and 10 µm, which prevent their use both in most of the the near-IR (1-5 µm) and mid-IR (5-25 µm) regions.Yttria-stabilized zirconia (YSZ) is a ceramic that has received a lot of attention due to its exceptional properties such as high hardness, high dielectric constant, chemical inertness, and high ionic conductivity at elevated temperatures. [5] In the powder form it is used to make coatings that are chemically inert and tolerant to mechanical wear and tear; for example, in cutting tools, chemical tank linings, and dental restorations. [6,7] It is also used as an electrolyte in solid oxide fuel cells. [8] Lately, there is a growing interest in using thin films and microspheres of YSZ for various photonic applications. [9][10][11][12][13] ENrG Inc. has commercialized 20 and 40 µm thick flexible substrates of 3 mol% yttria (Y 2 O 3 )-stabilized tetragonal zirconia (3YSZ) ceramic, which has also shown remarkable transparency in the near-IR and mid-IR while being translucent in the visible. [14,15] In this article, we propose and demonstrate for the first time that 3YSZ can be an ideal platform to implement next generation flexible IR nano-optic devices, such as plasmonic sensors and polarizers. We also show that it can be combined with graphene to make flexible transparent electrodes for the IR that can be used for cell culture spectroscopy and IR transparent shielding. [16,17] Infrared (IR) technologies have become increasingly relevant as they offer a wide range of applications, from thermal imaging to chemical and biological vibrational spectroscopy. Substrate materials, such as calcium fluoride and zinc selenide, are commonly used for IR optics. Unfortunately, they are typically fragile or hygroscopic, thus potentially producing problems during device fabrication and in the long-term functional operation. Here, yttria-stabilized zirconia (YSZ) ceramic is introduced as a flexible and stable platform for IR nano-optics. In particul...
