Wavelength independent detection and discrimination of a laser with a sensitivity of 140fW using self-coherence
David M. Benton, Andrew Ellis, Yiming Li
Wavelength independent detection and discrimination of laser radiation has been performed by detecting the "self coherence" of an incoming light source using interferometry with ph…

Beaconless Auto-Alignment for Single-Wavelength 5 Tbit/s Mode-Division Multiplexing Free-Space Optical Communications
Yiming Li, Gil Fernandes, David Benton +3
Mode-division multiplexing has shown its ability to significantly increase the capacity of free-space optical communications. An accurate alignment is crucial to enable such links…
