Compact focusing grating couplers for silicon-on-insulator integrated circuits [PDF]

open access: yes, 2007
—We report experimental results on compact and broadband focusing grating couplers, both in silicon-on-insulator (SOI) and gold on SOI. An eight-fold length reduction of the coupling structure from fiber to photonic wire in SOI, as com-pared to a linear ...

Construction of an optical test-bed for eLISA [PDF]

open access: yes, 2016
In the planned eLISA mission a key part of the system is the optical bench that holds the interferometers for reading out the inter-spacecraft distance and the test mass position.

Sustainable optics? A critical insight into biopolymer-enabled optics

open access: yesTetrahedron Green Chem, 2023
The use of biobased polymers or natural inorganic materials in place of synthetic polymers or liquid crystals derived from petroleum to fabricate optical components establishes the concept of “sustainable optics”, at least for what concerns the ...

Tuning Knobs for the NLC Final Focus

open access: yes, 2002
Compensation of optics errors at the Interaction Point (IP) is essential for maintaining maximum luminosity at the NLC. Several correction systems (knobs) using the Final Focus sextupoles have been designed to provide orthogonal compensation of linear ...

Optical microscope illumination analysis using through-focus scanning optical microscopy [PDF]

open access: yesOptics Letters, 2017
Misalignment of the aperture diaphragm present in optical microscopes results in angular illumination asymmetry (ANILAS) at the sample plane. Here we show that through-focus propagation of ANILAS results in a lateral image shift with a focus position.

Metasurface Optics for Full-color Computational Imaging

open access: yes, 2018
Conventional imaging systems comprise large and expensive optical components which successively mitigate aberrations. Metasurface optics offers a route to miniaturize imaging systems by replacing bulky components with flat and compact implementations ...
