How to Manufacture Photonic Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Dual‐Wavelength Vat Photopolymerization With Dissolvable, Recyclable Support Structures

open access: yesAdvanced Materials Technologies, EarlyView.
Selective solubility vat photopolymerization (SSVP) uses a single resin to produce dissolvable thermoplastics and insoluble thermosets in a single 3D print. Wavelength‐selective curing and thermal post‐processing provide 3D spatial control over dissolution kinetics, enabling dissolvable support structures and programmable dissolution profiles.

Frequency‐Dependent Demethylation of Cancer DNAs by High‐Power Terahertz Radiation

open access: yesAdvanced Photonics Research, EarlyView.
Effective demethylation of cancer DNA is successfully demonstrated by resonant irradiation with high‐power terahertz (THz) waves at the 10 mW level, combined with metamaterial‐based THz filters. The dependence of spectral filtering on demethylation indicates that the resonant frequency of 1.6 THz of cancer DNAs plays a crucial role in reducing the ...

Effect of Nanoparticle Distribution on Photothermal Absorption in Binary Mixtures of Colloidal Supraballs

open access: yesAdvanced Photonics Research, EarlyView.
This work combines molecular dynamics and finite‐difference time‐domain computational approaches to study the photothermal properties of melanin nanoparticle–based supra‐assemblies. Based on the results of this study, the binary mixtures of melanin and silica with higher concentrations of melanin and with more segregated levels of mixing are able to ...

High‐Isolation LCoS‐Based Optical Switch with Phase Hologram Parameter Optimization

open access: yesAdvanced Photonics Research, EarlyView.
A 1 × 9 liquid crystal on silicon (LCoS)‐based optical switch is experimentally demonstrated, revealing that the worst‐case port isolation exceeds 37 dB within the wavelength range of 1460–1540 nm. This work offers an alternative route for the development of optical switches with a large number of ports and high isolation, applicable to large‐capacity ...
