Imaging with Diffractive Axicons Rapidly Milled on Sapphire by Femtosecond Laser Ablation
Daniel Smith, Soon Hock Ng, Molong Han +4
Fabrication of large area (sub 1 cm cross-section) micro-optical components in a short period of time (approximately 10 min) and with lesser number of processing steps is highly de…
All femtosecond optical pump and X-ray probe: holey-axicon for free electron laser
V. Anand, J. Maksimovic, T. Katkus +21
We put forward a co-axial pump(optical)-probe(X-rays) experimental concept and show performance of the optical component. A Bessel beam generator with a central 100 micrometers-dia…
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…
Compact Three-Dimensional Quantitative Phase Contrast Imager
Vijayakumar Anand, Tomas Katkus, Denver Linklater +2
Detection of phase variations across optically transparent samples is often a difficult task. We propose and demonstrate a compact, lightweight and low cost quantitative phase cont…
A compact single channel interferometer to study vortex beam propagation
Sruthy J. Lathika, A. Vijayakumar, Shanti Bhattacharya
We propose and demonstrate a single channel interferometer that can be used to study how vortex beams propagate. The interferometer consists of a multifunctional diffractive optica…
Fresnel incoherent correlation holography with single camera shot
Vijayakumar Anand, Tomas Katkus, Stefan Lundgaard +4
Fresnel incoherent correlation holography (FINCH) is a self-interference based super-resolution three-dimensional imaging technique. FINCH in inline configuration requires an activ…
