Abstract-Efficient Design of Diffractive THz Lenses for Aberration Rectified Focusing via Modified Binary Search Algorithm

Sourangsu Banerji, Ashish Chanana, Hugo Condori, Ajay Nahata, and Berardi Sensale-Rodriguez

We experimentally demonstrate thin, error tolerant, and aberration corrected 3D printed diffractive 1D and 2D THz lenses for focusing THz beams with NA > 0.25 and an average efficiency greater than 75% (for all cases). Our work has relevance to THz lens design, and in general, THz imaging systems.
