Prior-information based super-resolution optical metrology of 2D nanoscale objects
Jin-Kyu So, Eng Aik Chan, Carolina Rendón-Barraza +2
Previous work has shown that optical metrology of one-dimensional objects, such as slit width, can achieve improved accuracy by using prior information from similar objects to trai…
Alignment-Free Nanometric Optical Metrology Enabled by Structured Light
Yu Wang, Benquan Wang, Eng Aik Chan +7
Advances in the semiconductor industry are driven by the development of increasingly compact devices featuring intricate etched geometries, the characterization of which essentiall…
Doppler-free selective reflection spectroscopy of electric-quadrupole transitions
Eng Aik Chan, Syed Abdullah Aljunid, Athanasios Laliotis +2
Electric-dipole-forbidden transitions play an important role as in quantum sensing, quantum information, and fundamental test in physics. As such, the development of novel and sens…
Dirac mass induced by optical gain and loss
Letian Yu, Haoran Xue, Ruixiang Guo +5
Mass is commonly regarded as an intrinsic property of matter, but modern physics reveals particle masses to have complex origins, such as the Higgs mechanism in high-energy physics…
Retrieving positions of closely packed sub-wavelength nanoparticles from their diffraction patterns
Benquan Wang, Ruyi An, Eng Aik Chan +6
Distinguishing two objects or point sources located closer than the Rayleigh distance is impossible in conventional microscopy. Understandably, the task becomes increasingly harder…
Picophotonics -- Subatomic Optical Localization Beyond Thermal Fluctuations
Tongjun Liu, Cheng-Hung Chi, Jun-Yu Ou +4
Despite recent tremendous progress in optical imaging and metrology, the resolution gap between atomic scale transmission electron microscopy and optical techniques has not been cl…
