Wavefront sensing from the image domain with the Oxford-SWIFT integral field spectrograph
, 2014 The limits for adaptive-optics (AO) imaging at high contrast and high resolution are determined by residual phase errors from non-common-path aberrations not sensed by the wavefront sensor, especially for integral field spectrographs, where phase ...

High‐Speed Multimode Fiber Imaging Using Binary‐Modulated Silicon Photonics Optical Phased Array
Laser &Photonics Reviews, EarlyView.A multimode fiber imaging system at 500 frames per second is experimentally demonstrated. It is enabled by a p‐i‐n diode‐based silicon photonics optical phased array. To simplify the electrical driving of p‐i‐n diodes, a binary modulation method with a costumed‐designed digital driver circuit is proposed. Reconstruction of each frame takes only 0.1 ms,

Hyperspectral wavefront sensing with a multicore fiber [PDF]
arXivSingle-shot hyperspectral wavefront sensing is essential for applications like spatio-spectral coupling metrology in high power laser or fast material dispersion imaging. Under broadband illumination, traditional wavefront sensors assume an achromatic wavefront, which makes them unsuitable. We introduce a hyperspectral wavefront sensing scheme based on

3D Dielectric Chiral Metamaterials Achieving Nondispersive Near‐Zero Ellipticity
Laser &Photonics Reviews, EarlyView.Broadband and high‐transmission‐efficiency optical activity (OA) is a critical functionality for numerous applications but is challenging to achieve. By engineering circularly polarized (CP) eigenstates in three‐dimensional (3D) dielectric helices, a 3D‐printed ceramic metamaterial is demonstrated for broadband OA with nondispersive near‐zero ...

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.
