Millimetre waves for the last mile

Reseachers at ETH Zurich have developed a modulator with which data transmitted via millimetre waves can be directly converted into light pulses for optical fibres. This could make covering the "last mile" up to the internet ...

New IR instrument searches for habitable planets

A new instrument to search for potentially habitable/inhabited planets has started operation at the Subaru Telescope. This instrument, IRD (InfraRed Doppler), will look for habitable planets around red dwarf stars. Astronomers ...

A laser that tracks like a hound

University of Adelaide researchers have created a laser that can "smell" different gases within a sample.

Researchers develop transportable optical atomic clock

Atomic clocks are no longer based on a microwave transition in cesium, instead operating with other atoms that are excited using optical frequencies. Some of these new clocks are portable. At its QUEST Institute, PTB is currently ...

One laser is enough

Gases in the environment can be spectroscopically probed fast and precisely using so-called dual frequency combs. Researchers at ETH have now developed a method by which such frequency combs can be created much more simply ...
