Desensitized telescope optical design: NSOS-α case study [PDF]

open access: yesEPJ Web of Conferences
NSOS-α is a 1.5-m aperture, F/1.55, wide field prime focus telescope for the Korea Astronomy & Space Science Institute (KASI) to discover and catalogue near-Earth asteroids, especially Potentially Hazardous Asteroids. Among the different optical designs,

All-optical combiner-splitter and gating devices based on straight waveguides [PDF]

open access: yes, 2007
A two-mode optical combiner-splitter device is designed based on all straight waveguides that maintains the integrity of the two modes during propagation and allows for an analytic analysis.

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 ...

Passive Athermal Optical Design Method Considering Thermal-Induced Surface Deformation

open access: yesPhotonics, 2021
Temperature variation not only results in changes in refractive index, radius, thickness, and air space, but also leads to surface deformation due to the mismatch in thermal expansion coefficients between glass and mechanical materials. However, existing

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

Nonlinear adiabatic optical isolator [PDF]

open access: yes, 2016
We theoretically propose a method for optical isolation based on adiabatic nonlinear sum frequency generation in a chirped quasi-phase-matching crystal with strong absorption at the generated sum frequency wave.

AR-HUD Optical System Design and Its Multiple Configurations Analysis

open access: yesPhotonics, 2023
The use of augmented reality head-up displays (AR-HUD) in automobile safety driving has drawn more and more interest in recent years. An AR-HUD display system should be developed to fit the vehicle and the complicated traffic environment in order to ...

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 ...

MEMS-actuated wavelength drop filter based on microsphere whispering gallery modes [PDF]

open access: yes, 2011
MEMS-enabled tuneable optical coupling between optical microsphere resonators and optical fibre waveguides is reported. We describe the design, fabrication and experimental characterization of a MEMS platform, based on electrothermal actuators, which ...
