“…Other exciting qualities are the rapid switching response times, [ 35 ] long lifetimes (>10 15 cycles), [ 36 ] and multiple stimuli that can be used to trigger the phase transition, such as electronically, [ 37 ] thermally, [ 38 ] and optically. [ 39 ] The exact classification of what solid‐state PCMs are depends on the field with an amorphous to crystalline transition being generally required, [ 40,41 ] but in nanophotonics, insulator‐to‐metal transitions (IMTs) such as that shown by vanadium dioxide (VO 2 ) have also qualified the material to be considered as a PCM. A key characteristic of the different PCMs is known as volatility, which is related to whether the external stimulus needs to be continuously applied (volatile) or not (nonvolatile) for the phase of the material to be maintained in a particular state.…”

In the field of nanophotonics, metasurfaces have come to the forefront in real‐world applications, owing to their accessible exotic optical properties that can be readily designed and fabricated using currently available techniques. The subwavelength dimensions and lightweight characteristics of metasurfaces are attractive qualities for the miniaturization of optical devices and are already exploited in devices that can rival, and sometimes even outperform, conventional bulky optics. Over the past decade, ample research has been undertaken to produce high‐performance metasurfaces with exciting optical properties that cannot be found in nature or achieved with conventional optics. To open the path to widely used devices in our everyday lives, the next obvious step for metasurfaces is the development of tunability. Herein, the techniques and development of applications of tunable metasurfaces are presented through the incorporation of active materials and controllable external stimuli, and the uncovered tunable characteristics are critically analyzed. The review rounds up by proposing the future directions and prospects for actively tunable metasurfaces and their potential practical applications.

As the quest for active photonic devices continues, materials with exotic and exploitable properties have become paramount to enable new advancements. In recent years, phase‐change materials (PCMs) have emerged as an exciting option that open new gateways for both fundamental physics and material science research, while also being applicable to actively tunable photonic devices. One PCM in particular, vanadium dioxide (VO2), has gained a lot of attention due to its interesting reversible insulator‐to‐metal transition that comes along with a drastic change in its optical properties. In this review, starting with a brief description and explanation of the origin of the exciting optical characteristics of VO2, we then present examples of the latest research trends of VO2 in photonic applications. This includes manipulation of the reflection, transmission, and absorption of light to produce color filters and near‐infrared perfect absorbers, as well as applications of telecommunications modulators, and we round up with applications in the energy field, in smart windows and adaptive radiative cooling. We conclude with a discussion about our views on the future perspectives for VO2 platforms in active photonic devices.

“…Intermediate metastable states and interplayed electronic and structural material aspects are involved. [ 87 ] In such a way, one of the main open questions is how to control them for enabling a nonvolatile optical switching performance with fast speed operation. In comparison with the heat‐driven devices, an electric field gating approach has been demonstrated to reach lower consumptions (few nJ) and faster switching speeds (down to ≈1 ns) but at the expense of higher optical losses and lower extinction ratios.…”

“…Vanadium dioxide (VO 2 ) also stands out as a promising material for photonics. [86,87] The key feature of this material is a reversible phase transition between an insulating and metallic state. At telecom wavelengths, the refractive index is drastically changed between both states, as shown in Figure 11a.…”

Nonvolatile switching is still a missing functionality in current mainstream silicon photonics complementary metal‐oxide‐semiconductor platforms. Fundamentally, nonvolatile switching stands for the ability to switch between two or more photonic states reversibly without needing additional energy to hold each state. Therefore, such a feature may push one step further the potential of silicon photonics by offering new ways of achieving photonic reconfigurability with ultrasmall energy consumption. Here, a detailed review of current developments that enable nonvolatile switching in silicon photonic waveguide devices is provided. Nonvolatility is successfully demonstrated either based on device engineering or by hybrid integration of silicon waveguides with materials exhibiting unique optical properties. Furthermore, several approaches with high potential for evolving toward a nonvolatile behavior with enhanced performance are also being explored. In most cases, many development steps are still necessary to ensure reliable devices. However, this research field is expected to progress in the coming years boosted by current and emerging applications benefiting from such functionality, such as new paradigms for photonic computing or advanced reconfigurable circuits for programmable photonic systems.
