Generation of a Focused THz Vortex Beam from a Spintronic THz Emitter with a Helical Fresnel Zone Plate

Posted by in category: particle physics

Similar to optical vortex beams, terahertz (THz) vortex beams (TVBs) also carry orbital angular momentum (OAM). However, little research has been reported on the generation of TVBs. In this paper, based on the detour phase technique, we design a series of spintronic terahertz emitters with a helical Fresnel zone plate (STE-HFZP) to directly generate focused TVBs with topological charges (TCs) of l = ±1, ±2 and ±3, respectively. The STE-HFZP is a hybrid THz device composed of a terahertz emitter and a THz lens, and it has a high numerical aperture (NA), achieving subwavelength focal spots. Its focus properties are surveyed systemically through accurate simulations. This STE-HFZP can also generate focused TVBs with higher order TCs.

New method minimizes alignment errors in microlens array production

Posted by in category: futurism

Double-sided microlens arrays (DSMLAs) play a crucial role in improving the performance of optical devices, supporting applications from advanced imaging systems to laser beam homogenization. However, traditional manufacturing methods often struggle with alignment errors that diminish the functionality and efficiency of these arrays.
