The vision of cars that drive or planes that fly themselves can only become true if the electronics on board can determine where they are in space, anytime and with reliable precision. In the aerospace sector, this job is given over to gyroscopes that measure light to check and stabilize the course of a vessel in flight. But such gyroscopes can be affected by certain material properties or by electrical or magnetic fields—and the consequences can be disastrous. This is why a German-Polish consortium has come together to develop a reliable means to transmit light to make gyroscopes less susceptible to interference. Their secret: Hollow-core fibers that can channel light with minimal loss.
