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.

Extreme Terahertz Nonlinearity of AlGaN/GaN‐Based Grating‐Gate Plasmonic Crystals

open access: yesAdvanced Optical Materials, EarlyView.
Plasmonic crystals based on grating‐gated 2D electron gas in AlGaN/GaN heterostructures provide a platform for strong light‐matter interaction. Pump‐probe experiments revealed strong terahertz nonlinearity leading to 45% increase in transmission at a fluence below 350 nJ cm−2.
