A High-Bandwidth Interplanetary Connection 99

sciencehabit writes "A new study suggests that by twisting laser light, scientists could pack enough information into interplanetary beams to speed up extraterrestrial communications to the multi-gigabit level. The pulses would be passed through a hologram or multimode optical fiber, which twists the light. On the other side, a telescope would focus the light and a second hologram, or fiber would decode the signal. That could allow much more data-rich communication between, say, Earth and probes on Mars, the researchers say. Closer to home, the approach could provide Internet links of 100 gigabits per second."
