Anisotropy analysis of bamboo and tooth using 4-angle polarization micro-spectroscopy
Meguya Ryu, Hsin-Hui Huang, Jitraporn Vongsvivut +6
To investigate the anisotropic properties of biomaterials, two distinct classes are considered: polymer-based (e.g., cellulose in plants) and crystalline-based (e.g., enamel in tee…
Interferometric microscale measurement of refractive index at VIS and IR wavelengths
Meguya Ryu, Simonas Varapnickas, Darius Gailevicius +6
Determination of refractive index of micro-disks of a calcinated (C in air) photo-resist SZ2080 was carried out using transmission and reflection spectros…
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…
Polylactic acid-nanocrystalline carbonated hydroxyapatite (PLA-cHAP) composite: preparation and surface topographical structuring with direct laser writing (DLW)
Edita Garskaite, Laurynas Alinauskas, Marian Drienovsky +7
The fabrication of polylactic acid (PLA)-carbonated hydroxyapatite (cHAP) composite material from synthesised phase pure nano-cHAP and melted PLA by mechanical mixing at 220-235°C…
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…
