Emerging nanophotonic biosensor technologies for virus detection

Nanophotonics, Volume 11, Issue 22, Page 5041-5059, December 2022., 2022
Abstract Highly infectious viral diseases are a serious threat to mankind as they can spread rapidly among the community, possibly even leading to the loss of many lives. Early diagnosis of a viral disease not only increases the chance of quick recovery, but also helps prevent the spread of infections.

Curvature prediction of long‐period fibre grating based on random forest regression

IET Optoelectronics, Volume 16, Issue 5, Page 225-233, October 2022., 2022
Abstract This study proposes a long‐period fibre grating (LPFG) curvature estimation method based on random forest regression (RFR) to address the shortcomings of the existing curvature evaluation method, namely, polynomial fitting; these shortcomings cause difficulty in achieving adequate model regularity and application universality.

Singularities splitting phenomenon for the superposition of hybrid orders structured lights and the corresponding interference discrimination method

Nanophotonics, Volume 11, Issue 7, Page 1413-1426, March 2022., 2022
Abstract It is the basic characteristic of pure vortex light that there is a phase singularity at the origin. Such a singularity may be multiple degenerate, which determines the order of vortex light. Singularities splitting phenomenon means that singularities no longer concentrate at the origin but distribute around the space, usually occurring in ...
