Prediction of wavefronts in adaptive optics to reduce servo lag errors using data mining [PDF]
XXXIV Symposium of OSI, ICOP, 2009, 2009 Servo lag errors in adaptive optics lead to inaccurate compensation of wavefront distortions. An attempt has been made to predict future wavefronts using data mining on wavefronts of the immediate past to reduce these errors. Monte Carlo simulations were performed on experimentally obtained data that closely follows Kolmogorov phase characteristics. An

Full‐Space Spin‐Controlled Four‐Channel Metalens With Equal Power Distribution and Broad Bandwidth
Laser &Photonics Reviews, EarlyView.In article xxxxx, Alex M. H. Wong and co‐authors propose a multifunctional full‐space metalens supporting power‐efficient, broadband operation for four spin‐controlled output channels. The metalens separates an incoming wave into four equi‐power, spin‐decoupled and function‐decoupled waves (two transmitted and two reflected).

Discrete Chiral Ballistic Polariton Laser
Laser &Photonics Reviews, EarlyView.Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.
