New Light Detector Could Allow Broadband in Space
Ker Than writes on Space.com:
Researchers at the Massachusetts Institute for Technology have developed a tiny light detector that could one day boost interplanetary communications to broadband speeds.More here.
The work could permit the transmission of color video between astronauts and satellites and scientists on Earth across interplanetary distances, something that is not practical with current technologies.
The new light detector improves detection efficiency to 57 percent at a wavelength of 1,550 nanometers—the same wavelength used by optical fibers on Earth to carry broadband signals to homes and offices. Currently, light detectors only absorb about 20 percent of the light they receive.
