New research in @NatureComms:
Led by @NPL, an international consortium has set a new record for comparing distant ultrastable lasers.
Find out more here about what this means for the next generation of atomic clocks:

Fascinating talk presented at CLEO EU today by EPic member Antonio Cutrona.
The talk was entitled "Self-Starting Temporal Cavity Solitons in a Laser Based Microcomb
Feel free to message any questions in DMs

An engaging talk from EPic member, Dr. Maxwell Rowley (@rowley_maxwell) in CLEO EU this evening.
The talk was entitled "Emergence of laser cavity-solitons in a microreseonator-filtered fiber laser"
DM us any questions!!

@acalalesina@PhotonicsMeetup @EPICSUSSEX No problem. So that is a way I am considering that it could be expanded in the future. For now we take a combination of values from literature and calculated values from the excited free-carrier concentration injected by the optical pump pulse.
We present the first characterisation of a photoexcited temporal boundary acting on a Black Silicon THz metasurface source. Previous Publication: https://t.co/mQG7UNORcG @PhotonicsMeetup @EPICSUSSEX #POM21ja#POM21meta
@acalalesina@PhotonicsMeetup @EPICSUSSEX Hi Antonio, thank you very much!
Of course, for the simulations here it is a 1D FDTD with a material dispersion given by the Drude model. We introduce the time-varying dynamics by adding an explicit time-dependence into the Drude plasma frequency and scattering rate.
We are looking for applicants for funded PhD positions in our lab! Please feel free to directly contact Dr. Alessia Pasquazi and Prof Marco Peccianti for more information: https://t.co/BZgi1NSi01 @PhysicsAtSussex @SPQRsussex @SussexQuantum@PhotonicsMeetup#POM21ja
@nanouschi @PhotonicsMeetup @EPICSUSSEX Thank you yes it is quite straightforward, the needles themselves form spontaneously as the Silicon is etched. And the density / geometry can be tuned with the plasma properties / etching time etc.
@nanouschi @PhotonicsMeetup @EPICSUSSEX Hi Ann-Katrin, thank you for your interest. The black silicon is a random assortment of nanocones that traps >96% of impinging light. It is etched by inductively coupled plasma-reactive ion etching in a SF6/02 plasma. #POM21ja#POM21meta@PhotonicsMeetup
We present experimental results mapping the existence region of cavity-solitons in a dual-cavity microcomb laser. See previous publications: https://t.co/NUoTHK4KWi & https://t.co/XU9BPa62yQ
