“…A variety of nonlinear absorption mechanisms across many material systems have been used, including reverse saturable absorption in organic/organometallic polymers, [8,15] multi-photon absorption in liquid crystals [16] and graphene and its derivatives, [17] free-carrier absorption in semiconductors, [18] nonlinear absorption in correlated materials, [19] and many others. [6,9,20,21] Despite their popularity, absorptive limiters are often not ideal because absorption of intense incident light can damage the limiter itself, for example, via melting, sputtering, delamination, or ablation.…”

Optical limiters are nonlinear devices that feature decreasing transmittance with increasing incident optical intensity, and thus can protect sensitive components from high‐intensity illumination. The ideal optical limiter reflects rather than absorbs light in its active (“limiting”) state, minimizing risk of damage to the limiter itself. Previous efforts to realize reflective (rather than absorbing) limiters were based on embedding nonlinear layers into relatively thick multilayer photonic structures, resulting in substantial fabrication complexity, reduced speed and, in some instances, limited working bandwidth. In this paper, these tradeoffs are overcome by using the insulator‐to‐metal transition (IMT) in vanadium dioxide (VO2) to achieve intensity‐dependent modulation of resonant transmission through aperture antennas. Due to the large change of optical properties across the IMT, low‐quality‐factor resonators are sufficient to achieve high on–off ratios in the transmittance of the limiter. As a result, our ultrathin reflective limiter (thickness ≈1/100 of the free‐space wavelength) is broadband in terms of operating wavelength (>2 µm at 10 µm) and angle of incidence (up to ≈50° away from the normal). Our analysis of the experimental results via opto‐thermal simulations provides insight into limiter performance and is a useful guidance for further engineering efforts.

As a new class of 2D materials, MXenes have attracted a lot of interest because of their prominent performance in versatile applications, such as batteries, supercapacitors, catalysts, electronics, and optics. In this work, an all‐optical modulator using MXene Ti3C2Tx deposited on a microfiber is proposed. By inserting an MXene‐deposited phase shifter into one arm of a Mach–Zehnder interferometer, the MXene Ti3C2Tx absorbs the control light and generates heat, which induces significant refractive index changes through strong light–matter interactions and thermo‐optic effects. In this study, a maximum phase shift of 16π is obtained, and an efficient all‐optical switch with an extinction ratio of more than 18.53 dB and a rise time constant of 4.10 ms are demonstrated. The advantages of this modulator include its all‐fiber content, low cost, ease of integration, and compactness. All‐optical modulators based on thermo‐optical effects will play an active role in the future of optical communications and optical information processing.
