Inverse-designed stretchable metalens with tunable focal distance

Template-Stripped Tunable Plasmonic Devices on Stretchable and Rollable Substrates

We use template stripping to integrate metallic nanostructures onto flexible, stretchable, and rollable substrates. Using this approach, high-quality patterned metals that are replicated from reusable silicon templates can be directly transferred to polydimethylsiloxane (PDMS) substrates. First we produce stretchable gold nanohole arrays and show that their optical transmission spectra can be m...

Optofluidic lens with tunable focal length and asphericity

Adaptive micro-lenses enable the design of very compact optical systems with tunable imaging properties. Conventional adaptive micro-lenses suffer from substantial spherical aberration that compromises the optical performance of the system. Here, we introduce a novel concept of liquid micro-lenses with superior imaging performance that allows for simultaneous and independent tuning of both foca...

Stretchable Ag electrodes with mechanically tunable optical transmittance on wavy-patterned PDMS substrates

We report on semi-transparent stretchable Ag films coated on a wavy-patterned polydimethylsiloxane (PDMS) substrate for use as stretchable electrodes for stretchable and transparent electronics. To improve the mechanical stretchability of the Ag films, we optimized the wavy-pattern of the PDMS substrate as a function of UV-ozone treatment time and pre-strain of the PDMS substrate. In addition, ...

Stretchable plasmonic substrate with tunable resonances for surface-enhanced Raman spectroscopy

Transparent and flexible functional nanostructures are very important for flexible electronic devices, such as roll-up displays, handheld portable devices, and wearable electronics, and have attracted growing scientific and industrial interest in recent years. We produced a facile and flexible hybrid structure by conjugating plasmonic nanostructures onto the surface of a poly (dimethylsiloxane)...
