Experimental and theoretical evaluation of an ultrafast multihop packet-switched optical TDM network test bed [PDF]

open access: yes, 1998
Just recently, a network that has integrated many optical time-division multiplexing (TDM) technologies such as 100-Gbits/s packet compression and ultrafast demultiplexing has been demonstrated.

Ultralight Ultrafast Enzymes**

open access: yesAngewandte Chemie, 2023
Abstract Inorganic materials depleted of heavy stable isotopes are known to deviate strongly in some physicochemical properties from their isotopically natural counterparts. Here we explored for the first time the effect of simultaneous depletion of the heavy carbon, hydrogen, oxygen and nitrogen isotopes on the ...

Ultrafast line detector

open access: yesJournal of Electronic Imaging, 2022
This article introduces the fastest line detector so far published in the literature. This algorithm is 14.88 times faster than the next fastest line detector, the EDLines, and 94.7 times faster than the line segment detector. It is hundreds of times faster and more reliable than the Standard Hough Transform.

Ultrafast terahertz magnetometry [PDF]

open access: yesNature Communications, 2020
AbstractA material’s magnetic state and its dynamics are of great fundamental research interest and are also at the core of a wide plethora of modern technologies. However, reliable access to magnetization dynamics in materials and devices on the technologically relevant ultrafast timescale, and under realistic device-operation conditions, remains a ...

Ultrafast Charge Dynamics in Bulk Zinc Oxide under Intense Photoexcitation

open access: yesPhotonics, 2023
The photo-induced charge dynamics of textbook wide-bandgap semiconductor ZnO have been investigated on the picosecond time-scale. We performed optical Pump-THz Probe experiments in order to measure the dielectric constant of the material after high ...

Control of Frequency Combs with Passive Resonators

open access: yesSensors, 2023
Tailored optical frequency combs are generated by nesting passive etalons within mode-locked oscillators. In this work, the oscillator generates a comb of 6.8 GHz with 106 MHz side-bands.
