Single Light Beam Coherent Optical Communication with Stokes Parameters

Optical Communication with Weak Coherent Light Fields

Experimental determination of two-point Stokes parameters for a partially coherent broadband light beam

Standoff and arms-length detection of chemicals with single-beam coherent anti-Stokes Raman scattering.

The detection of chemicals from safe distances is vital in environments with potentially hazardous or explosive threats, where high sensitivity and fast detection speed are needed. Here we demonstrate standoff detection of several solids, liquids, and gases with single-beam coherent anti-Stokes Raman scattering. This approach utilizes a phase coherent ultrabroad-bandwidth femtosecond laser to p...

Coherent Optical Communication Systems

The rapid evolution of long-haul optical communications systems, witnessed in the last five years, is due to the gradual adoption of spectrally efficient, multilevel modulation formats, in conjunction with polarization division multiplexing (PDM) and coherent intradyne detection assisted by digital signal processing (DSP). The objective of this tutorial chapter is to briefly review the operatin...
