Magnifying absolute instruments for optically homogeneous regions [PDF]
Phys. Rev. A 84, 031801(R) (2011), 2011 We propose a class of magnifying absolute optical instruments with a positive isotropic refractive index. They create magnified stigmatic images, either virtual or real, of optically homogeneous three-dimensional spatial regions within geometrical optics.

Optical-component-only adaptive optics
Optics Letters, 2021 This Letter introduces a technique for performing binary adaptive optics, which is carried out by optical components only, without the help of any electronic or optoelectronic device. In this technique, the interferogram produced by a point diffraction interferometer modulates a light-driven crystal. The modulated light-driven crystal may produce pupil-

Adaptive optics based on machine learning: a review
Opto-Electronic Advances, 2022 Adaptive optics techniques have been developed over the past half century and routinely used in large ground-based telescopes for more than 30 years. Although this technique has already been used in various applications, the basic setup and methods have ...

Exceptional points in optics and photonics
Science, 2019 Exceptional points in optics Many complex systems operate with loss. Mathematically, these systems can be described as non-Hermitian. A property of such a system is that there can exist certain conditions—exceptional points—where gain and loss can be ...

Physics-informed neural networks for inverse problems in nano-optics and metamaterials. [PDF]
Optics Express, 2019 In this paper, we employ the emerging paradigm of physics-informed neural networks (PINNs) for the solution of representative inverse scattering problems in photonic metamaterials and nano-optics technologies.

An Optical Interference Suppression Scheme for TCSPC Flash LiDAR Imagers
Applied Sciences, 2019 This paper describes an optical interference suppression scheme that allows flash light detection and ranging (LiDAR) imagers to run safely and reliably in uncontrolled environments where multiple LiDARs are expected to operate concurrently. The issue of

Optical frequency combs generated mechanically [PDF]
, 2016 It is shown that a highly equidistant optical frequency comb can be generated by the parametric excitation of an optical bottle microresonator with nanoscale effective radius variation by its natural mechanical vibrations.

Horocycles of Light in a Ferrocell
Condensed Matter, 2021 We studied the effects of image formation in a device known as Ferrocell, which consists of a thin film of a ferrofluid solution between two glass plates subjected to an external magnetic field in the presence of a light source.
