Article Title: One-shot TSOM with a multi-task learning model for simultaneous dimension measurement and defect inspection
Article Snippet: Dimension measurement and defect inspection of nanostructure devices are essential tasks in large-scale integrated circuit (IC) manufacturing.. Through-focus scanning optical microscopy (TSOM) can image nondestructively at high sensitivity and has been strongly encouraged by the IEEE International Roadmap for Devices and Systems (IRDS): Metrology, but it does not fulfill the efficiency requirements for IC fabrication measurements.. We developed and evaluated a one-shot TSOM system and TSOM multi-task learning model (TSOM MTL).

Article Title: Design, Analysis, and Implementation of the Subdivision Interpolation Technique for the Grating Interferometric Micro-Displacement Sensor
Article Snippet: In our previous work [27], we em- Photonics 2025, 12, 64 9 of 11 ployed a polarization phase-shifting optical path to extract two sinusoidal signals with a quadrature phase shift, and combined it with the interpolation circuit, achieving a diffraction grating displacement sensor with nanometer-level resolution.

Article Title: Topological Photonic Lattice for Uniform Beam Splitting, Robust Routing, and Sensitive Far-Field Steering.
Article Snippet: Far-field optical beam steering is a fast-growing technology for communications, spatial ranging, and detections.. Nonmechanical optical phased arrays based on straight waveguides have been studied recently, where the beam emission angle to the propagation axis can be scanned by conveniently tuning the wavelength.. However, the dispersion of the waveguide limits the wavelength sensitivity of beam steering and the deliberately created emitters inevitably introduce in-line backscattering on-chip.
