Laser-based technology and sophisticated modulation schemes could help deliver on future demands for high data volumes, finds Andy Extance
Designers, builders and operators of free-space networks can leverage LWIR quantum cascade lasers (QCLs) to achieve multi Gb/s data transfer rates. Find out how
Download this White Paper from Wavelength Electronics to find out how a team of researchers realised error-free, free-space live video broadcasting using a room temperature QCL with a wavelength of 8.1µm.
The filter represents a breakthrough in the integration of functionality and performance in radio frequency photonic signal processors
The sale is expected to advance Microsoft’s cloud infrastructure
The light source used in the experiment is a custom-designed optical chip
The project demonstrated a transmission speed in free-space of up to one terabit per second (equal to 1,000 gigabits per second) on a single wavelength and over a distance of 53 kilometres
The work will be done as part of DARPA's 'Space-based adaptive communications node' programme
The chipset has integrated lasers directly driven from a digital signal processor without the use of any external driver chip, providing exceptional total system performance
As microscopes become ever more powerful, a growing band of businesses are racing to make the latest technologies more accessible and more affordable, reports Rebecca Pool
Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
Newly discovered fundamental rules have been embedded into software to dramatically optimise the design of photonic integrated circuits
