Universal relations for coupling of optical power between microresonators and dielectric waveguides [PDF]

, 2000
The most basic and generic configuration, which consists of a unidirectional coupling between a ring resonator and a waveguide, is considered. The fundamental working equations required to describe the associated power transfer are derived and the ...

Comparing Optical Packet Switching And Optical Burst Switching

Daffodil International University Journal of Science and Technology, 1970
The switching is an important part of the telecommunication networks over the years for transferring and handling voice and data through the traditional switching nodes existing in the telecommunication networks. Various developments were seen in the recent years which resulted in increasing data transfer capabilities of the transmission networks all ...

Chirality in Nonlinear Optics and Optical Switching [PDF]

Molecular Crystals and Liquid Crystals, 1993
Chirality in molecular opto-electronics is limited sofar to the use of optically active liquid crystals and a number of optical phenomena are related to the helical macroscopic structure obtained by using one enantiomer, only. In this paper, the use of chirality in nonlinear optics and optical switching is demonstrated.

Harmonic oscillations and their switching in elliptical optical waveguide arrays

, 2011
We have studied harmonic oscillations in an elliptical optical waveguide array in which the coupling between neighboring waveguides is varied in accord with a Kac matrix so that the propagation constant eigenvalues can take equally spaced values.

Optical burst switching with large switching overhead [PDF]

2006 IEEE International Conference on Communications, 2006
The optical burst switching (OBS) schemes to date assume that the switching overhead at intermediate nodes is either negligible or can be considered as part of the processing delay of the control packet. In this paper, we will show that the switching overhead can have a significant impact on the performance of OBS.

Ultrafast optical circuit switching for data centers using integrated soliton microcombs [PDF]

Nature Communications, 2020
Due to the slowdown of Moore’s law, it will become increasingly challenging to efficiently scale the network in current data centers utilizing electrical packet switches as data rates grow.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Full vectorial analysis of polarization effects in optical nanowires [PDF]

, 2012
We develop a full theoretical analysis of the nonlinear interactions of the two polarizations of a waveguide by means of a vectorial model of pulse propagation which applies to high index subwavelength waveguides.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Optically controlled energy transfer in stacked and coplanar polycyclic chromophores [PDF]

, 2010
In the search for enhanced control over the process of resonance energy transfer in multichromophore molecular systems, all-optical mechanisms offer many significant advantages over other systems.
