Optical Design of a Miniaturized 10× Periscope Zoom Lens for Smartphones [PDF]

open access: yesMicromachines, 2023
The size of the optical zoom system is important in smartphone camera design, especially as it governs the thickness of the smartphone. We present the optical design of a miniaturized 10× periscope zoom lens for smartphones.

Opto-electronic high order feedback neural network [PDF]

open access: yes, 1990
A novel neural network design, in which nonlinearities are created by feedback, is described. It is called the HOFNET. The design is suitable for optical implementation because it is tolerant of the limited dynamic ranges present in optical systems.

Optical interconnection networks based on microring resonators [PDF]

open access: yes, 2012
Optical microring resonators can be integrated on a chip to perform switching operations directly in the optical domain. Thus they become a building block to create switching elements in on-chip optical interconnection networks, which promise to overcome

The Ascendency of Numerical Methods in Lens Design

open access: yesJournal of Imaging, 2018
Advancement in physics often results from analyzing numerical data and then creating a theoretical model that can explain and predict those data. In the field of lens design, the reverse is true: longstanding theoretical understanding is being overtaken ...

Polarization-preserving confocal microscope for optical experiments in a dilution refrigerator with high magnetic field [PDF]

open access: yes, 2010
We present the design and operation of a fiber-based cryogenic confocal microscope. It is designed as a compact cold-finger that fits inside the bore of a superconducting magnet, and which is a modular unit that can be easily swapped between use in a ...

Optical Optimization of Tandem Solar Cells: A Systematic Review for Enhanced Power Conversion

open access: yesNanomaterials, 2023
Tandem solar cells (TSCs) perform a better adaptation of the incident photons in different-energy-level bandgap materials, and overcome the Shockley–Queisser limit, but they require advanced control over the management of light for optimum performance ...
