A 2D nanosphere array for atomic spectroscopy

Atomic spectroscopy: a review.

Enhanced Optical Cross Section via Collective Coupling of Atomic Dipoles in a 2D Array.

Enhancing the optical cross section is an enticing goal in light-matter interactions, due to its fundamental role in quantum and nonlinear optics. Here, we show how dipolar interactions can suppress off-axis scattering in a two-dimensional atomic array, leading to a subradiant collective mode where the optical cross section is enhanced by almost an order of magnitude. As a consequence, it is po...

The performance of 2D array detectors for light sheet based fluorescence correlation spectroscopy.

Single plane illumination microscopy based fluorescence correlation spectroscopy (SPIM-FCS) is a new method for imaging FCS in 3D samples, providing diffusion coefficients, transport, flow velocities and concentrations in an imaging mode. SPIM-FCS records correlation functions over a whole plane in a sample, which requires array detectors for recording the fluorescence signal. Several types of ...

2D linear array device as a quality assurance tool in brachytherapy applications

Background: External beam radiotherapy and brachytherapy plays a vital role in the management of cancer cervix.  High dose rate brachytherapy is being presently used worldwide for the brachytherapy applications. At present, 2-Dimensional linear array detectors   are the most common QA tool used for pretreatment patient specific quality assurance in external beam radiotherapy alon...

Periodic Nanowell Array using Template-Assisted Nanosphere Lithography

Nanosphere lithography (NSL) has been studied as the effective method of fabricating nano-scale array. This paper presents template-assisted NSL to obtain high-quality crystal in regularity and coverage. A periodic array of 100 nm deep nano trenches with two different widths, 400 and 450 nm was fabricated by nano imprint lithography (NIL), and used as the template. When polystyrene nanospheres ...
