A millimeter-wave antireflection coating for cryogenic silicon lenses [PDF]

open access: yes, 2007
We have developed and tested an antireflection (AR) coating method for silicon lenses at cryogenic temperatures and millimeter wavelengths. Our particular application is a measurement of the cosmic microwave background.

Low scatter and ultra-low reflectivity measured in a fused silica window [PDF]

open access: yes, 2013
We investigate the reflectivity and optical scattering characteristics at 1064\,nm of an antireflection coated fused silica window of the type being used in the Advanced LIGO gravitational-wave detectors.

Enhanced Absorption in InP Nanodisk Arrays on Ultra-Thin-Film Silicon for Solar Cell Applications

open access: yesPhotonics, 2022
The photovoltaic (PV) market today is dominated by silicon (Si)-based solar cells, which, however, can be improved in performance and cost by developing technologies that use less material.

Exactly solvable models : a solution to different problems of laser matter interaction [PDF]

open access: yes, 2004
With the increasing use of ultrashort laser pulses and nanoscale-materials, one is regularly confronted to situations in which the properties of the media supporting propagation are not varying slowly with time (or space).

Graded index and randomly oriented core-shell silicon nanowires for broadband and wide angle antireflection

open access: yesAIP Advances, 2011
Antireflection with broadband and wide angle properties is important for a wide range of applications on photovoltaic cells and display. The SiOx shell layer provides a natural antireflection from air to the Si core absorption layer.

Wide-bandwidth mode-hop-free tuning of extended-cavity GaN diode lasers [PDF]

open access: yes, 2005
We present a new approach for extended-cavity diode-laser tuning to achieve wide mode-hop-free tuning ranges. By using a multiple piezoactuated grating mount, the cavity length and grating angle in the laser can be adjusted independently, allowing mode ...

Single-Step Fabrication of Longtail Glasswing Butterfly-Inspired Omnidirectional Antireflective Structures

open access: yesNanomaterials, 2022
Most bio-inspired antireflective nanostructures are extremely vulnerable and suffer from complicated lithography-based fabrication procedures. To address the issues, we report a scalable and simple non-lithography-based approach to engineer robust ...

Quantum vacuum photon-modes and superhydrophobicity [PDF]

open access: yes, 2015
Nanostructures are commonly used for developing superhydrophobic surfaces. However, available wetting theoretical models ignore the effect of vacuum photon-modes alteration on van der Waals forces and thus on hydrophobicity.
