Physics-informed neural networks for inverse problems in nano-optics and metamaterials. [PDF]

open access: yesOptics 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.

A Review of Compressive Sensing in Information Security Field

open access: yesIEEE Access, 2016
The applications of compressive sensing (CS) in the field of information security have captured a great deal of researchers' attention in the past decade. To supply guidance for researchers from a comprehensive perspective, this paper, for the first time,

Exceptional points in optics and photonics

open access: yesScience, 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 ...

Adaptive optics based on machine learning: a review

open access: yesOpto-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 ...

Silicon-on-Nitride Waveguide With Ultralow Dispersion Over an Octave-Spanning Mid-Infrared Wavelength Range

open access: yesIEEE Photonics Journal, 2012
The proposed silicon-on-nitride (SON) waveguide exhibits an ultrabroadband (4200 nm), low chromatic dispersion in the mid-infrared (MIR) wavelength region from 2430 to 6630 nm. It has two zero-dispersion wavelengths within the span.

Noncanonical quantum optics [PDF]

open access: yes, 2000
Modification of the right-hand-side of canonical commutation relations (CCR) naturally occurs if one considers a harmonic oscillator with indefinite frequency. Quantization of electromagnetic field by means of such a non-CCR algebra naturally removes the

Low-Power All-Optical Switch Based on Time-Reversed Microring Laser

open access: yesIEEE Photonics Journal, 2012
An all-optical switch based on an absorbing microring resonator laterally coupled to two waveguides is described theoretically using the coupling of modes in time formalism and numerically using the finite-difference time-domain method.

Polarization singularities from unfolding an optical vortex through a birefringent crystal [PDF]

open access: yes, 2004
Optical vortices (nodal lines and phase singularities) are the generic singularities of scalar optics but are unstable in vector optics. We investigate experimentally and theoretically the unfolding of a uniformly polarized optical vortex beam on ...

Multidimensional quantum entanglement with large-scale integrated optics [PDF]

open access: yesScience, 2018
Large-scale integrated quantum optics The ability to pattern optical circuits on-chip, along with coupling in single and entangled photon sources, provides the basis for an integrated quantum optics platform. Wang et al.
