Pure-amplitude holograms for high-efficiency generation of phase radial grating based radial carpet beams: Theory and experiments under plane-wave and Gaussian illumination
Saifollah Rasouli, Somaye Fathollazade, Mohammad Mohammadi
This study introduces a pure-amplitude hologram (PAH) for generating radial carpet beams (RCBs), which are conventionally produced using pure phase radial gratings (PRGs). The holo…

A wafer-scale ultrasensitive programmable chiroptical sensor
Haoyu Xie, Jichao Fan, Zarif Ahmad Razin Bhuiyan +6
Chiroptical enantioselective sensing is gaining traction across various applications. However, intrinsic molecular chiroptical responses are weak, and existing amplification approa…
