Harnessing optical micro-combs for microwave photonics

open access: yes, 2018
In the past decade, optical frequency combs generated by high-Q micro-resonators, or micro-combs, which feature compact device footprints, high energy efficiency, and high-repetition-rates in broad optical bandwidths, have led to a revolution in a wide ...

All-Optical Switching Demonstrated with Photoactive Yellow Protein Films

open access: yesBiosensors, 2021
Integrated optics (IO) is a field of photonics which focuses on manufacturing circuits similar to those in integrated electronics, but that work on an optical basis to establish means of faster data transfer and processing. Currently, the biggest task in

Monolayer MoS2 for nanoscale photonics

open access: yesNanophotonics, 2020
Transition metal dichalcogenides are two-dimensional semiconductors with strong in-plane covalent and weak out-of-plane interactions, resulting in exfoliation into monolayers with atomically thin thickness.

Four-photon scattering in birefringent fibers [PDF]

open access: yes, 2008
Four-photon scattering in nonlinear waveguides is an important physical process that allows photon-pair generation in well defined guided modes, with high rate and reasonably low noise. Most of the experiments to date used the scalar four-photon scattering process in which the pump photons and the scattered photons have the same polarization.

Photon - Photon Interaction

open access: yes, 2018
The famous 1927 Solvay Conference was considered a turning point in the world of Physics. The scientific realists like Albert Einstein had lost and the instrumentalists like Niels Bohr had won the fundamental conflict. Since then Physics has followed the path of the instrumentalists in which Quantum Physics has been determined by the concept of ...

Biophotonics: a marriage of sciences [PDF]

open access: yes, 2002
Biophotonics denotes a combination of biology and photonics, with photonics being the science and technology of generation, manipulation, and detection of photons, quantum units of light.

Dispersive Fourier Transformation for Versatile Microwave Photonics Applications [PDF]

open access: yes, 2014
: Dispersive Fourier transformation (DFT) maps the broadband spectrum of an ultrashort optical pulse into a time stretched waveform with its intensity profile mirroring the spectrum using chromatic dispersion.

A Multithread Nested Neural Network Architecture to Model Surface Plasmon Polaritons Propagation

open access: yesMicromachines, 2016
Surface Plasmon Polaritons are collective oscillations of electrons occurring at the interface between a metal and a dielectric. The propagation phenomena in plasmonic nanostructures is not fully understood and the interdependence between propagation and

Photon-photon correlations and entanglement in doped photonic crystals [PDF]

open access: yesPhysical Review A, 2001
We consider a photonic crystal (PC) doped with four-level atoms whose intermediate transition is coupled near-resonantly with a photonic band-gap edge. We show that two photons, each coupled to a different atomic transition in such atoms, can manifest strong phase or amplitude correlations: One photon can induce a large phase shift on the other photon ...
