“…In summary, we experimentally demonstrated the effects of 1D photonic crystals on the optical transmission of VO 2 nanostructures by depositing VO 2 thin films on SiO 2 /TiO 2 based DBRs. Therefore, this experimental work confirms the main theoretical prediction of an earlier theoretical paper [29] on observing near perfect optical absorption in the near-IR spectrum in such vanadium dioxide/1D photonic crystal based composite nanostructures. Besides, we also report temperature controlled optical transmission based on the MIT of VO 2 .…”

“…Zhu et al recently reported the use of an anti-reflection coating to enhance the visible transmittance of VO 2 film [28]. There are reports of the theoretical prediction of absorption enhancement using this type of nanocomposite photonic structure on DBRs as well [29,30]. Here we have used a 1D photonic crystal based DBR, fabricated with alternating SiO 2 /TiO 2 layers along with VO 2 (M) nano-composite thin films.…”

The effect of 1D photonic crystals on the optical transmission of VO2 is studied by depositing thin films of VO2 nanoparticles on SiO2/TiO2 distributed Bragg reflectors (DBRs) in the near-infrared (IR) spectrum as per the earlier theoretical predictions of Rashidi et al (2018 J. Phys. D: Appl. Phys. 51 375102). Monoclinic VO2 nanoparticles with tuned crystallinity are synthesized using a facile solution processing method. Moderately crystalline (MC) and highly crystalline (HC) VO2 nanostructures are obtained by varying the synthesis temperature and post-growth annealing conditions. Both the MC VO2 and HC VO2 films exhibit the expected reduction in optical transmission in the IR region due to the structural phase transition from monoclinic (insulator) to rutile (metallic) around the critical temperature of 68 °C. By combining VO2 films on a 40% transmitting DBR structure, the average optical transmission decreases further to ~20%. The number of stacks of DBRs plays a key role in such an effective reduction of optical transmission in the IR. When the number of stacks of DBRs is further increased from 4 to 7, the optical transmission of metallic VO2 films on DBRs nearly vanishes in the near-IR spectrum in such vanadium dioxide 1D photonic crystal based composite photonic structures. Such a temperature-controlled, enhanced, broad band optical response could provide a promising design for VO2 nanoparticle based hybrid photonic absorbers for various smart window applications.

The artificial crystal structures have been attracted tremendous research efforts; the well studied being optical photonic crystals and acoustic phononic crystals [138][139][140][141][142][143][144][145][146][147][148][149][150][151][152].

Magnonics, an emerging research field, aims to control and manipulate spin waves in magnetic materials and structures. However, the current understanding of spin waves remains quite limited. This review attempts to provide an overview of the anomalous behaviors of spin waves in various types of magnetic materials observed thus far by inelastic light scattering experiments. The anomalously large asymmetry of anti-Stokes to Stokes intensity ratio, broad linewidth, strong resonance effect, unique polarization selection, and abnormal impurity dependence of spin waves are discussed. In addition, the mechanisms of these anomalous behaviors of spin waves are proposed. spectroscopy is applied for studying vibrational properties of materials. However, due to the anomalous behaviors of spin wave scattering comparing with vibrational scattering, Raman spectroscopy study of spin wave is difficult and limited. In this paper, we present a review of anomalous behaviors of spin waves observed by inelastic light scattering experiments, especially by Raman spectroscopy. The large asymmetry of anti-Stokes to Stokes intensity ratio, broad linewidth, strong resonance effect, unique polarization selection, and abnormal impurity dependence of spin waves are discussed, and a proposed model for the mechanisms of spin flip, spin relaxing, and spin wave scattering is presented for understanding these anomalous behaviors of spin waves. In addition, two magnonic crystal structures are proposed for manipulating spin waves through analyses of the abnormal impurity dependence of spin waves. The review of the anomalous behaviors of spin waves and the proposed models provide the directions for easier experimental study of spin waves by inelastic light scattering, which will be useful for raising the research efforts for investigating spin waves. This is important for the emerging research of magnonics, which has received extensive interests in the modern magnetism research community.

The optical properties of vanadium dioxide (VO2) can be tuned via metal-insulator transition. In this work, different types of one-dimensional photonic structure-based microcavities that embed vanadium dioxide have been studied in the spectral range between 900 nm and 2000 nm. In particular, VO2 has been sandwiched between: i) two photonic crystals made of SiO2 and ZrO2; ii) two aperiodic structures made of SiO2 and ZrO2 that follow the Thue-Morse sequence; iii) two disordered photonic structures, made of SiO2 and ZrO2 in which the disorder is introduced either by a random sequence of the two materials or by a random variation of the thicknesses of the layers; iv) two four material-based photonic crystals made of SiO2, Al2O3, Y2O3, and ZrO2. The ordered structures i and iv show, respectively, one and two intense transmission valleys with defect modes, while the aperiodic and disordered structures ii and iii show a manifold of transmission valleys due to their complex layered configurations. The metal-insulator transition of VO2, controlled by temperature, results in a modulation of the optical properties of the microcavities.
