Abstract: This study proposes a method to create a ring array using birefringence (BR) and conical refraction (CR), where a circularly polarized beam is first divided into 2m sub-beams in m BR crystals and then transformed… read more here.

Abstract: Abstract Topologically structured light carrying orbital angular momentum (OAM) has emerged as a powerful tool for nano-photonics and biomedical optics, yet conventional integer-charge Laguerre–Gaussian (LG) beams suffer from rotational degeneracy that limits diagnostic precision. Here,… read more here.
