Researchers have demonstrated a "time telescope" that could squeeze much more information into the data packets sent around the internet.Rather than focusing information-carrying light pulses in space, like a normal lens, it focuses them in time.
The telescope comprises laser beams that combine in a tiny silicon structure to compress the pulses.
A prototype device, described in Nature Photonics, boosted the data rate of telecoms-wavelength pulses by 27 times.
E.g. A laser pulse having a
spread of colours within it
Reading between the lines what they seem to be building is transitions from the electronic domain to the optical domain that can sustain faster rates. BUT I might have well missed the ball in the smokescreen called journalism.
Essentially, it's the same as modulating a carrier wave to create radio broadcasts - whether amplitude modulation or frequency modulation is used, the actual transmitted signal occupies a frequency range that straddles the carrier frequency.
As for the rest of the article, I may read it again, but it certainly baffled me the first time.

If a laser is switched on and off fast enough (getting close to the frequency of the emitted light)
Still, I'm pretty sure you need to think in the quantum domain no matter what when it comes to lasers. This due to the way the photons of laser light are created (simplified: a decay of an electron between two quantum energy levels) and their specific characteristics.
