Quantum Cascade Lasers
Steady progress turns multi-wavelength quantum cascade laser arrays into a powerful versatile source for next-generation spectroscopy and stand-off detection systems.
A new paradigm – functional and nonlinear optical metasurfaces
Optical metasurfaces offer a wealth of useful functionalities. Their nonlinear effects can be enhanced with the help of metasurface engineering.
Electromagnetic absorbers: from narrow to broad
Chinese scientists have given an overview on the principle of different types of narrowband EM absorbers.
Combed radio frequencies: an overview
Optical frequency comb technology for ultra-broadband radio-frequency photonics.
Ultra-black silicon makes an excellent broadband absorber
A novel ultra-black broadband absorber concept based on a needle-like silicon nanostructure has been developed by Jena researchers.
Controlling light with light
A new approach to control light with light without the need for optical nonlinearity has been suggested by a Russian-British research group.
The new look of LPR: making the best of your work
Laser & Photonics Reviews has a new look! The first issue with new cover pages making full use of background covering pictures was released this month.
A new level for continuous-wave terahertz lasers
A robust surface emitting continuous-wave terahertz quantum cascade laser has been realized in a two-dimensional photonic crystal structure.
