Abstract
The system and method of the present invention advantageously enable controllable light extraction from optical fiber waveguides and offer highly configurable light signal guidance and control capabilities, as well as additional advantageous features associated with waveguides, by providing, in various exemplary embodiments thereof, a multitude of novel techniques by which the parameters relating to utilization of various light signals (such as direction of their emission, magnitude of the emission, physical surface area of the emission, etc.), can be readily controlled and configured as a matter of design choice. Additionally, the inventive system and method, in various exemplary embodiments thereof, also enable and facilitate selective configuration of, and/or control over, various characteristics of the light signals guided/controlled/extracted thereby, such as the signals' wavelength, polarization, intensity, amplitude, etc. To achieve the above-noted beneficial functions, the system and method of the present invention utilize a physical property of a standard, or a specialty, chiral optical fiber to scatter light signals entering the fiber in directions away from the fiber cor…
