Photonic crystals articles from across Nature Portfolio

Photonic crystals are periodic optical structures that can control the flow of light. Multiple reflections from surfaces separated by a distance similar to the wavelength prevent an optical beam from propagating through the crystal. Photonic crystal devices can therefore force light around sharp bands or even trap it entirely.

Photonic crystals with rainbow colors by centrifugation-assisted assembly of colloidal lignin nanoparticles

Photonic crystals are often prepared by assembly of particles into periodically arranged structures, but it is challenging to fabricate these materials using lignin nanoparticles. Here, the authors report the use of centrifugation to fabricate photonic crystals with rainbow structural colors.

Strongly enhanced light–matter coupling of monolayer WS₂ from a bound state in the continuum

Combining a tungsten disulfide monolayer and a topologically protected bound state in the continuum formed by a one-dimensional photonic crystal, strong light–matter interaction enhancement and large exciton–polariton nonlinearities at room temperature are demonstrated.

Two-dimensional semiconducting SnP₂Se₆ with giant second-harmonic-generation for monolithic on-chip electronic-photonic integration

2D semiconductors with nonlinear optical properties hold promise for multifunction integration in electronic-photonic integrated circuits. Here, the authors report the synthesis of 2D SnP₂Se₆ and its integration with a SiN photonic platform, showing strong odd-even layer-independent second harmonic generation activity at 1550 nm and broadband photoresponse.

Laser writing of spin defects in nanophotonic cavities

Using direct laser writing with a nanosecond pulsed laser operating at above-bandgap photon energies, we demonstrate the selective formation of spin defects in photonic crystal cavities in 4H-silicon carbide and their in situ characterization.

Writing above the bandgap

Above-bandgap, nanosecond laser pulses enable the localized in situ writing of spin defects in prefabricated nanophotonic cavities. The approach preserves defect and cavity mode properties, key requirements towards cavity–emitter coupling in quantum networks.

Reciprocal topological photonic crystals allow backscattering

Topological photonics has promised new devices that are resistant to backscattering, leading to lower loss, greater nonlinearity, and smaller footprint. New research shows that in reciprocal photonic crystals, backscattering is unavoidable, implying that breaking reciprocity is essential to leveraging photonic Chern insulators.

Developing nanophotonic structures that are stable in air and at high temperatures

A concept to mitigate temperature-related degradation in nanophotonic materials is implemented in photonic crystals of perovskite and rocksalt oxides. The developed structures can withstand temperatures of 1,100 °C in air and offer wavelength-selective control of thermal emission. Additionally, an algorithm is used to identify alternative material candidates for such structures.

A 2D material-based liquid crystal for deep-ultraviolet light modulation

Suspensions of 2D hexagonal boron nitride show an anomalously large specific Cotton–Mouton coefficient, enabling the fabrication of a magnetically tuneable and stable birefringent optical device. This device serves as a transmissive light modulator with wavelengths entering the ultraviolet (UV)-C region, representing a technological advance in deep-UV modulation.
