TLDR
In this article, a linear four element adaptive heterodyne optical receiver array employing semiconductor lasers is described, which adaptively adjusts the phase of each subaperture IF signal to correct for wavefront tilt and distortion and non-uniform optical and RF path delays across the array by phase-locking each channel to a reference channel.Abstract:

Coherent beam combining of large number of PM fibres in 2-D fibre array
TL;DR: In this paper, the authors reported coherent combining of a record 48 PM fibres in a phased array configuration, and the resulting Strehl ratio degrades by 1000 fibres, achieving the state-of-the-art performance.

TL;DR: In this paper, a system and method for networked high-speed data communication through free space is described, which includes one or more central networks, which contain one or multiple laser modulated with high speed data to illuminate with laser light areas surrounding the central network.
ThE SEARCH FOR EXTRATERRESTRIAL INTELLIGENCE (SET!) IN ThE OPTICAL SPECTRUM: A REVIEW
TL;DR: In this paper, the authors strongly suggest that the microwave rationale behind modern-day SETI lore is suspect, and that our search for electromagnetic signals from extraterrestrial technical civilizations may be doomed to failure because we are "tuned to the wrong frequencies".

TL;DR: Fields of view and overall efficiencies far larger than those predicted by the antenna theorem for conventional heterodyne systems are obtained.
