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…
3D laser printing by ultra-short laser pulses for micro-optical applications: towards telecom wavelengths
Meguya Ryu, Vygantas Mizeikis, Junko Morikawa +5
Three dimensional (3D) fast (< 0.5 hour) printing of micro-optical elements down to sub-wavelength resolution over 100 micrometers footprint areas using femtosecond (fs-)laser osci…
Polarisation of THz synchrotron radiation: from its measurement to control
Meguya Ryu, Denver Linklater, William Hart +7
Polarisation analysis of synchrotron THz radiation was carried out with a standard stretched polyethylene polariser and revealed that the linearly polarised (horizontal) component…
Nanoscale precision of 3D polymerisation via polarisation control
Sima Rekstyte, Tomas Jonavicius, Darius Gailevicius +4
A systematic analysis of polarization effects in a direct write femtosecond laser 3D lithography is presented. It is newly shown that coupling between linear polarization of the wr…
