Generation of Terahertz Superimposed Perfect Vortex Beams
نویسندگان
چکیده
A terahertz (THz) superimposed perfect vortex (SPV) beam is generated by using a designed optimal phase element (SOPE) at 0.3 THz. As the topological charge changes, ring radius of THz SPV beams remains almost constant in experiment, whose relative error only 0.96%. The property confirmed. intensity profile with equally spaced breakpoints. carried can be judged directly identifying number linearly related to radial wave vector, which adjusted. Such have promising applications for fiber communication systems based on beams.

Generation of perfect vortex and vector beams based on Pancharatnam-Berry phase elements
Perfect vortex beams are the orbital angular momentum (OAM)-carrying beams with fixed annular intensities, which provide a better source of OAM than traditional Laguerre-Gaussian beams. However, ordinary schemes to obtain the perfect vortex beams are usually bulky and unstable. We demonstrate here a novel generation scheme by designing planar Pancharatnam-Berry (PB) phase elements to replace al...
متن کاملGeneration of multiterawatt vortex laser beams.
We report the fabrication of large-area phase masks on thin fused-silica substrates that are suitable for shaping multiterawatt femtosecond laser beams. We apply these phase masks for the generation of intense femtosecond optical vortices. We further quantify distortions of the vortex beam patterns that result from several common types of mask defects.
متن کاملPolarization modulation in optoelectronic generation and detection of terahertz beams
Compared with the conventional laser amplitude modulation with a lock-in amplifier, the optical polarization modulation in optoelectronic generation and detection of a free-space terahertz ~THz! radiation provides up to twofold increase of the dynamic range. The total laser power for the optoelectronic generation of THz beams can be fully utilized. © 1999 American Institute of Physics. @S0003-6...
متن کاملGeneration of optical vortex beams by nonlinear wave mixing.
It is shown that optical vortex beams can be generated from a non-vortex fundamental beam by an optical frequency conversion process taking place within a twisted nonlinear photonic crystal. This is done without any first-order (linear) refractive optics. Through such a proposed structure, all-optical switching of vortices with different helicities is made possible, as well as the simultaneous ...
