10 Gbit/s free space data transmission at 9 m wavelength with unipolar quantum optoelectronics
arXiv:2110.06572
Abstract
The realization of high-frequency unipolar quantum optoelectronic devices enables the demonstration of high bitrate free space data transmission in the second atmospheric window. Data-bits are written onto the laser emission using a large bandwidth amplitude modulator that operates by shifting the absorption of an optical transition in and out of the laser frequency.
