For free-space optical (FSO) communications through the turbulent atmospheric channel, multi-spatial-mode photoncounting detectors can provide an attractive high-sensitivity receiver solution. However, multi-mode detection also increases optical back

We demonstrate improved angular acceptance for low-loss narrowband optical filtering for high-sensitivity photon-counting free-space applications. Using a silicon etalon, a GHz-class passband with 230% greater low-loss angular acceptance is achieved.

Optical propagation through the ocean encounters significant absorption and scattering; the impact is exponential signal attenuation and temporal broadening, limiting the maximum link range and the achievable data rate, respectively. MIT Lincoln Labo

Narrow-beam laser communication (lasercom) can enable high-rate, long-range undersea communication. Light in the beam is absorbed and scattered by suspended particulates, altering the spatial, angular, and temporal properties of the transmitted light
