Semiconductor-based narrow-line and high-brilliance 193-nm laser system for industrial applications

Wilfried Noell, Toralf Scharf, Xiaolong Wang, Raoul Kirner, Andreas Vetter

We present a novel industrial-grade prototype version of a continuous-wave 193 nm laser system entirely based on solid state pump laser technology. Deep-ultraviolet emission is realized by frequency-quadrupling an amplified diode laser and up to 20 mW of o ...

Full Color Generation Using Silver Tandem Nanodisks

Christian Santschi, Olivier Martin, Hua Zhao, Chen Yan, Jingwen Zhang, Xiaolong Wang

Plasmonic effects associated with metallic nanostructures have been widely studied for color generation. It became apparent that highly saturated and bright colors are hard to obtain, and very small nanostructures need to be fabricated. To address this iss ...

Twisting Fluorescence through Extrinsic Chiral Antennas

Olivier Martin, Chen Yan, Xiaolong Wang

Plasmonic antennas and planar structures have been undergoing intensive developments in order to control the scattering and absorption of light. One specific class, extrinsic chiral surfaces, that does not possess 2-fold rotational symmetry exhibits strong ...

Strong Improvement of Long-Term Chemical and Thermal Stability of Plasmonic Silver Nanoantennas and Films

Christian Santschi, Olivier Martin, Xiaolong Wang

Silver (Ag) nanostructures and thin films are advantageous plasmonic materials as they have significantly lower losses than gold (Au). Unfortunately, Ag nanostructures suffer from poor chemical and thermal stability, which limit their applications. Here, t ...

Advanced Plasmonic Nanostructures for Engineering Fluorescence Applications

Xiaolong Wang

The appeal of plasmonics lies in the unique properties of coinage metal nanoparticles to strongly confine and enhance electromagnetic fields at the subwavelength. A simple 50 nm colloidal plasmonic particle can not only break the classical diffraction limi ...

Revisiting Newton’s rings with a plasmonic optical flat for high-accuracy surface inspection

Olivier Martin, Xiaolong Wang, Jie Bian

Two parallel optical surfaces often exhibit colorful fringes along the lines of equal thickness because of the interference of light. This simple phenomenon allows one to observe subwavelength corrugations on a reflective surface by simply placing on it a ...
