Ultra-high-capacity wireless communication by means of steered narrow optical beams.
Philos Trans A Math Phys Eng Sci

The optical spectrum offers great opportunities to resolve the congestion in radio-based communication, aggravated by the booming demand for wireless connectivity. High-speed infrared optical components in the 1500 nm window have reached high levels of sophistication and are extensively used already in fibre-optic networks. Moreover, infrared light beyond 1400 nm is eye-safe and is not noticeable by the users.

- The study focuses on enhancing space division multiplexing transmission systems by increasing spatial mode channels within a few-mode fiber.
- Low differential mode group delays (DMGD) are achieved using a low-DMGD fiber, allowing for efficient transmission over a distance of 4.45 km.
- A time-domain-SDM receiver captures 10 spatial mode channels using only 3 coherent receivers, and a new encoding technique shows potential for a 10x improvement in transmission capacity.
