On capacity of optical communications over a lossy bosonic channel with a receiver employing the most general coherent electro-optic feedback control [PDF]
, 2017 We study the problem of designing optical receivers to discriminate between multiple coherent states using coherent processing receivers---i.e., one that uses arbitrary coherent feedback control and quantum-noise-limited direct detection---which was ...

Spatial coherence of forward-scattered light in a turbid medium [PDF]
, 1999 We study spatially coherent forward-scattered light propagating in a turbid medium of moderate optical depth (0-9 mean free paths). Coherent detection was achieved by using a tilted heterodyne geometry, which desensitizes coherent detection of the ...

Digital self-coherent detection
Optics Express, 2008 We review recent progresses on digital self-coherent detection of differential phase-shift keyed (DPSK) signal using orthogonal differential direct detection followed by high-speed analog-to-digital conversion and digital signal processing (DSP). Techniques such as data-aided multisymbol phase estimation for receiver sensitivity enhancement, unified ...
