Modes of twisted fibers
The mode structure in weakly guiding twisted fibers is investigated. It is demonstrated that in the case of small pitch of twist in the model without the spin-orbit coupling modes of twisted fibers ar...
Computer processing of fiber-vortex sensor data
It was considered three methods of the computer processing of the spiral interference pattern being the result of two field superposition: the field carrying over an optical vortex and scattered from ...
Itis experimentally and theoretically studied the generated vortex process bythe optical wedge and the optical knife. After those opticaltransparencies it takes place the birth and death vortices events.By adjusting the slope angle of the transparency and thebeam truncation depth, the Gaussian beam may be converted intothe singular beam transferring a single vortex.
