“…The tunable resonant frequency of optical antennas would be useful for dynamic control and favorable to realizing antenna-based spatial light modulators, or active displays. Similar approaches (to couple plasmonic structures into VO 2 to achieve controllable resonance) have been reported by various groups [8]- [17]. VO 2 metamaterials with tunable properties have also been studied, and the field is well poised for growth [18]- [21].…”

Materials that undergo an electronic phase change in a reversible manner open up new directions for research in light-matter interactions and photonic devices. The highly tunable dielectric properties, along with the spatial control of insulating and metallic domains, create photonic-crystal-like environments to control light propagation. In this brief overview, recent advances in photonics that utilize solid-state phase-change systems such as vanadium dioxide (VO 2 ) and chalcogenides are discussed. The controllable optical properties such as the refractive index and the optical conductance between two distinct phases in these materials pave the way for switchable photonic devices with memory. Furthermore, the intermediate states with the coexistence of two phases in the vicinity of phase transition in these materials behave as a tunable metamaterial with extraordinary optical properties that is promising for applications such as perfect absorbers.

“…3(d), it was found that the redshift of the valley is unconspicuous for the structure with double layer Al:ZnO film, indicating the destructive interference effects of the buffer layer. It was believed that the localized surface-plasmon resonance and the controllable optical phase can be attributed to the complex refractive indices change of the films 24, 41, 42 . The variation of the optical spectra of Al:ZnO film is subtle and can be ignored.…”

Active and widely controllable phase transition optical materials have got rapid applications in energy-efficient electronic devices, field of meta-devices and so on. Here, we report the optical properties of the vanadium dioxide (VO2)/aluminum-doped zinc oxide (Al:ZnO) hybrid n-n type heterojunctions and the corresponding electro-optic performances of the devices. Various structures are fabricated to compare the discrepancy of the optical and electrical characteristics. It was found that the reflectance spectra presents the wheel phenomenon rather than increases monotonically with temperature at near-infrared region range. The strong interference effects was found in the hybrid multilayer heterojunction. In addition, the phase transition temperature decreases with increasing the number of the Al:ZnO layer, which can be ascribed to the electron injection to the VO2 film from the Al:ZnO interface. Affected by the double layer Al:ZnO, the abnormal Raman vibration mode was presented in the insulator region. By adding the external voltage on the Al2O3/Al:ZnO/VO2/Al:ZnO, Al2O3/Al:ZnO/VO2 and Al2O3/VO2/Al:ZnO thin-film devices, the infrared optical spectra of the devices can be real-time manipulated by an external voltage. The main effect of joule heating and assistant effect of electric field are illustrated in this work. It is believed that the results will add a more thorough understanding in the application of the VO2/transparent conductive film device.

“…This property has been used to propose improved designs for VO 2 -based smart windows, standing on the optical absorption by localized surface plasmon resonances in VO 2 NPs above the transition temperature [92]. VO 2 can also be used as an active matrix for switching the response of plasmonic NSs of other nature [93].…”
