Identification of the Intrinsic Dielectric Properties of Metal Single Atoms for Electromagnetic Wave Absorption

open access: yesNano-Micro Letters, 2021
Atomically dispersed metals on N-doped carbon supports (M–N x Cs) have great potential applications in various fields. However, a precise understanding of the definitive relationship between the configuration of metal single atoms and the dielectric loss

Distribution networks and electrically controllable couplers for integrated optics [PDF]

open access: yes, 1974
The power distribution as a function of propagation distance in a network of coupled optical waveguides is determined for several interesting cases. An electrically controllable coupler is proposed and analyzed in detail.

An efficient integrated two-color source for heralded single photons

open access: yesNew Journal of Physics, 2013
We present a pulsed and integrated, highly non-degenerate parametric down-conversion (PDC) source of heralded single photons at telecom wavelengths, paired with heralding photons around 800 nm.

Improved non-linear devices for quantum applications

open access: yesNew Journal of Physics, 2021
In this paper, we review the state of the art of mode selective, integrated sum-frequency generation devices tailored for quantum optical technologies. We explore benchmarks to assess their performance and discuss the current limitations of these devices,

Robust quantum state engineering through coherent localization in biased-coin quantum walks [PDF]

open access: yes, 2018
We address the performance of a coin-biased quantum walk as a generator for non-classical position states of the walker. We exploit a phenomenon of coherent localisation in the position space --- resulting from the choice of small values of the coin ...

Fiber cavities with integrated mode matching optics [PDF]

open access: yes, 2017
In fiber based Fabry-P\'{e}rot Cavities (FFPCs), limited spatial mode matching between the cavity mode and input/output modes has been the main hindrance for many applications. We have demonstrated a versatile mode matching method for FFPCs.

Over response correction of optical fiber sensor in radiation measurement

open access: yesAIP Advances, 2022
In radiation measurement, optical fiber sensors (OFS) have many advantages compared to commercial dosimeters, including high spatial resolution. Due to the OFS measurement principle (fluorescence), the recorded measurement results differ from the ...
