Showing that strong-field physics can be simulated using an optical waveguide.
Slowing down electromagnetic waves via hyperfine terahertz metamaterials
A new approach for multispectral plasmon-induced transparency metamaterials
Controlling matter with light
For a recent colloquium at the University of Bath, Professor Andrea Cavalleri spoke about his work on ‘controlling solid phases with light’.
Plasmonic electron sources
Low intensity laser excitation of solid targets with periodically ordered nano-objects generates electrons with energies as high as 300eV
Nora Berrah: interactions between photons and molecules
We talk to Professor Nora Berrah from the University of Connecticut.
Entrepreneurship and Science – An interview with Robert Scholten
We talk to Professor Robert Scholten about his research at the University of Melbourne and making lasers as the co-founder of MOGLabs
Image of the week: heating a hydrogen jet
Liquid hydrogen in action.
Image of the week: that’s no moon
But nor is it a space station. While it might bear some resemblance to a certain location from a famous film franchise, today’s Image of the Week entry is actually a visual representation of the properties of a laser pulse…. Read More ›
Light bite: 100s science video & the IYL
This week we bring you a video feature on recent research into new optical fibres and take the opportunity to showcase some top research from across the JPhys series on light and optical technology as part of the International Year of Light. Lasers, invisibility cloaks, plasmas, nanophotonics and more
Quantum dots for optoelectronic applications
Semiconductor quantum dots (QDs) exhibit unique properties, such as superior tuneability and sensitivity, due to their three-dimensional quantum confinement. These features make them particularly attractive for optoelectronic applications, such as lasers, solar cells and photodetectors.
Frontiers of Free Electron Laser Science
JPhysB has begun publishing Frontiers of Free-Electron Laser Science II. Click the title to find out more.
Image of the week – electron spectrum
Lasers can be used to induce the emission of electrons from ions through a process called photodetachment. Particularly interesting to those working in strong field atomic physics is photodetachment in negative ions by femtosecond laser pulses. In a recent paper… Read More ›
Image of the week: femtosecond laser writing
This installment of image of the week features the work of Toney Teddy Fernandez et al, who, in a recent JPhysD paper, investigated the properties of optical waveguides using femtosecond lasers. Several parameters of the laser writing process, including the writing direction, affect the transient… Read More ›
Special Issue on Filamentation
Last week JPhysB published a Special Issue on the subject of Filamentation. In their editorial Guest Editors Ruxin Li, Howard Milchberg and Andre Mysyrowicz explain: Twenty years after its first observation in air, the filamentation of ultrashort optical pulses remains… Read More ›
JPhysB in 2015
JPhysB had a great 2014 and has an exciting year ahead of it in 2015. Click here to find out more about the changes we’ve got coming up.
Spotlight: attosecond physics and an attosecond lighthouse
Attosecond physics studies processes that occur on a time scale of around 10-18 seconds. That’s 0.00000000000000001 seconds, which is to 1 second what a second is to the age of the universe. Pulses of light with attosecond duration could be… Read More ›
