Nature Photonics Magazine Presents a World-record
Micrometer-sized Converter of Electrical into Optical Signals / Future
Energy-efficient Chip-to-chip Optical Communication Links
Thanks to optical signals, mails and data can be transmitted
rapidly around the globe. But also exchange of digital information between
electronic chips may be accelerated and energy efficiency might be increased by
using optical signals. However, this would require simple methods to switch
from electrical to optical signals. In the Nature Photonics magazine,
researchers now present a device of 29 µm in length, which converts signals at
a rate of about 40 gigabits per second. It is the most compact high-speed phase
modulator in the world.
