Topologically controlled multiskyrmions in photonic gradient-index lenses
Yijie Shen, Chao He, Zipei Song +8
Skyrmions are topologically protected quasiparticles, originally studied in condensed-matter systems and recently in photonics, with great potential in ultra-high-capacity informat…
On-chip beam rotators, adiabatic mode converters, and waveplates through low-loss waveguides with variable cross-sections
Bangshan Sun, Fyodor Morozko, Patrick S. Salter +14
Photonics integrated circuitry would benefit considerably from the ability to arbitrarily control waveguide cross-sections with high precision and low loss, in order to provide mor…
Vectorial adaptive optics
Chao He, Jacopo Antonello, Martin J. Booth
Adaptive optics normally concerns the feedback correction of phase aberrations. Such correction has been of benefit in various optical systems, with applications ranging in scale f…
Polarisation optics for biomedical and clinical applications: a review
Chao He, Honghui He, Jintao Chang +3
Many polarisation techniques have been harnessed for decades in biological and clinical research, each based upon measurement of the vectorial properties of light or the vectorial…
Revealing complex optical phenomena through vectorial metrics
Chao He, Jintao Chang, Patrick S. Salter +17
Advances in vectorial polarisation-resolved imaging are bringing new capabilities to applications ranging from fundamental physics through to clinical diagnosis. Imaging polarimetr…
Full Poincaré polarimetry enabled through physical inference
Chao He, Jianyu Lin, Jintao Chang +10
While polarisation sensing is vital in many areas of research, with applications spanning from microscopy to aerospace, traditional approaches are limited by method-related error a…
Active compensation of extrinsic polarization errors using adaptive optics
Yuanyuan Dai, Chao He, Jingyu Wang +5
We present a scheme for active compensation of complex extrinsic polarization perturbations introduced into an optical system. Imaging polarimeter is used to measure the polarizati…
Complex vectorial optics through gradient index lens cascades
Chao He, Jintao Chang, Qi Hu +10
Graded index (GRIN) lenses are commonly used for compact imaging systems. It is not widely appreciated that the ion-exchange process that creates the rotationally symmetric GRIN le…
