Frequency converter implementing an optical analogue of the cosmological redshift

open access: yes, 2010
According to general relativity, the frequency of electromagnetic radiation is altered by the expansion of the universe. This effect--commonly referred to as the cosmological redshift--is of utmost importance for observations in cosmology.

Two Means of Compensating Fiber Nonlinearity Using Optical Phase Conjugation [PDF]

open access: yesarXiv, 2003
Two fiber lines may compensate each other for nonlinearity with the help of optical phase conjugation. The pair of fiber lines and the optical signals in them may be either mirror-symmetric or translationally symmetric about the conjugator.

Optical vortex soliton with self-defocusing Kerr-type nonlocal nonlinearity [PDF]

open access: yesarXiv, 2008
We develop one numerical method to compute the optical vortex soliton with self-defocusing Kerr-type nonlocal nonlinearity. With the numerical simulation method, the propagation and interaction properties of such optical vortex solitons are investigated.

A note on optical activity and extrinsic chirality [PDF]

open access: yesarXiv, 2015
It has been assumed that optical activity can be measured by illuminating alternatively a material with left- and right- handed circular polarized light and analyzing the differential response. This simple and intuitive approach is in general incorrect, and has led to misleading idea that extrinsic chirality involves optical activity.

All-Lossy Quasi-Guided Dual-Mode Optical Waveguide Exhibiting Exceptional Singularities [PDF]

open access: yesarXiv, 2018
We explore exceptional points (EP) in a dual-mode symmetric planar optical waveguide with transverse variation of inhomogeneous loss profile; where modal evolution alongside an EP is reported in the context of selective optical mode conversion.

An Alternative Derivation of Johannisson's Regular Perturbation Model [PDF]

open access: yesarXiv, 2012
We provide here an alternative derivation of the generalization of the nonlinear Turin model for dispersion unmanaged coherent optical links provided in Johannisson's report [arXiv:1205.2193]

Direct synthesis of strong grating couplers for efficient integrated optical beam forming [PDF]

open access: yesarXiv, 2014
Removed by arXiv administrators because submission violated the terms of arXiv's license agreement.

Embarking on a skyrmion Odyssey [PDF]

open access: yesarXiv
Optical Skyrmions, as an emergent cutting-edge topic in optics and photonics, extend the concept of non-singular topological defects to topological photonics, providing extra degrees of freedom for light-matter interaction manipulations, optical metrologies, optical communications, etc..

Trapping and unlimited delay of light pulses at microscale without distortion [PDF]

open access: yesarXiv, 2015
A tunable bottle microresonator can trap an optical pulse of the given spectral width, hold it as long as the material losses permit, and release without distortion.
