Article
Monitoring the laser-induced melting and solidification dynamics of Ge upon laser irradiation is an enormous challenge due to the short penetration depth of its liquid phase. In this work, real-time pump-probe experiments in combination with finite element calculations have been employed to investigate the melting and solidification dynamics of ger...

Plasmonic metasurfaces based on the extraordinary optical transmission effect (EOT) can be designed to efficiently transmit specific spectral bands from the visible to the far-infrared regimes, offering numerous applications in im-portant technological fields such as compact multispectral imaging, biological and chemical sensing, or color displays....

Direct laser writing of amorphous lines in crystalline silicon has the potential for becoming a flexible alternative to silicon-on-insulator technology for photonic integrated circuits. Yet, the maximum amorphous layer thickness achieved is 60 nm, which is below the requirements for waveguiding at telecom wavelengths. Here, the authors report on di...
Article
Laser-induced periodic surface structures (LIPSS) can readily be fabricated in virtually all types of materials and benefit from an efficient parallel patterning strategy that exploits self-organization. The wide range of different LIPSS types with different spatial scales and symmetries is continuously growing, addressing numerous of applications....
Conference Paper
Laser induced periodic surface structures (LIPSS) can be studied as waveplates due to the birefringence induced by the nanoripples, with easy fabrication since they are fabricated in a one-step process by laser, where LIPSS geometry are defined by the characteristics of the laser and the substrate. The optical properties of these waveplates are def...
Conference Paper
LIPSS are an emergent method of fabricating functional surfaces. A high repetition rate ultrashort pulsed laser was used to generate LIPSS on metallic surfaces. Different combinations of the processing parameters were tested to study their effect on the period of the LIPSS. Additionally, the influence of the repetition rate (laser frequency) on the...
Conference Paper
Surface nanostructuring has received increasing attention in recent years due to the wide range of applications in which it offers advantages. Particularly, Laser-Induced Periodic Surface Structures (LIPSS) have proven useful for surface functionalization. LIPSS are periodic formations generated in most materials when irradiated with linearly polar...
Conference Paper
Birefringence induced by nanoripples generated by laser (Laser Induced Periodic Surface Structures, LIPSS), enables their use as polarization gratings. Their fabrication is simple, as LIPSS geometry is defined by the characteristics of the laser and the substrate in a one-step process. In this work LIPPS generated on stainless steel have been used...

Article
Full-text available
We demonstrate a rapid, accurate, and convenient method for tailoring the optical properties of diamond surfaces by employing laser induced periodic surface structuring (LIPSSs). The characteristics of the fabricated photonic surfaces were adjusted by tuning the laser wavelength, number of impinging pulses, angle of incidence and polarization state...
Conference Paper
Full-text available
Fabricating reflective waveplates using nanostructured surfaces has taken great interest in recent years due to their simple structure: a diffractive grating composed of ripples with subwavelength period. The surface ripples act as an artificial birefringent material: the anisotropy of the surface cor-rugation generates a phase delay between two pe...
