Photonic advantage of optical encoders

open access: yesNanophotonics, 2023
Abstract Light’s ability to perform massive linear operations in parallel has recently inspired numerous demonstrations of optics‐assisted artificial neural networks (ANN). However, a clear system‐level advantage of optics over purely digital ANN has not yet been established.

Quantum nonlinear optics — photon by photon [PDF]

open access: yesNature Photonics, 2014
The realization of strong interactions between individual photons is a long-standing goal of both fundamental and technological significance. Scientists have known for over half a century that light fields can interact inside nonlinear optical media, but the nonlinearity of conventional materials is negligible at the light powers associated with ...

Flexible dispersion engineering using polymer patterning in nanophotonic waveguides

open access: yesScientific Reports, 2023
We demonstrate the engineering of waveguide dispersion by lithographically patterning the polymer cladding on silicon nitride waveguide resonators. Both normal and anomalous dispersion, ranging from − 462 to 409 ps/nm/km, can be achieved for the same ...

Nondestructive Detection of an Optical Photon [PDF]

open access: yesScience, 2013
Nondestructive Photon Detection The click of a photon detector is the usual method for detecting a photon and can be sufficiently sensitive to detect even a single photon. Such a detection process is, however, destructive—the photon is annihilated. Reiserer et al. (

Hyperspectral screen-image-synthesis meter with scattering-noise suppression

open access: yesScientific Reports, 2023
The screen image synthesis (SIS) meter was originally proposed as a high-speed measurement tool, which fused the measured data from multiple sample-rotational angles to produce a whole-field measurement result. However, it suffered from stray light noise

Adaptive focal lengths in white light focusing Fresnel lenses enabled by reflective-type and phase-only spatial light modulator

open access: yesScientific Reports, 2023
Fresnel zone plates (FZPs) are widely used in integrated optical systems to meet new cutting-edge demands for photonic integration and device miniaturizing. However, their use in applications of cross-scale fabrication still faces several obstacles, such
