Tilted black-Si: ~0.45 form-birefringence from sub-wavelength needles
Darius Gailevicius, Meguya Ryu, Reo Honda +14
The self-organised conical needles produced by plasma etching of silicon (Si), known as black silicon (b-Si), create a form-birefringent surface texture when etching of Si orientat…

Photonic Crystal Spatial Filters Fabricated by Femtosecond Pulsed Bessel Beam
Darius Gailevičius, Vytautas Purlys, Kestutis Staliunas
We propose and experimentally demonstrate femtosecond direct laser writing with Bessel beams for the fabrication of photonic crystals with spatial filtering functionality. Such fil…
