We reviewed recent intelligent methods for metasurface designs including machine learning, physics-information neural network, and topology optimization method.
Metal halide perovskites have emerged as promising materials platform for integrated photonics applications. On chip nano-lasers and detectors owing to their ultracompact physical sizes, highly localized coherent output, and efficient waveguiding, are promising building blocks for fully integrated nanoscale photonic and optoelectronic devices.
We present how direct-laser-writing can be utilized to fabricate ultra-thin light-weight planar diffractive optics with graphene as the base material. (Inset scale bar: 1 mm).
New function of photochromic spiropyran molecules for initiating two-photon photopolymerization via direct laser writing holds great potential in fast 3D printing technology.
This paper reviews recent advances that have pushed the boundary of far-field chemical microscopy in terms of spatial resolution as well as their applications in biomedical research, material characterization, environmental study, etc.
Insights from recent THz emission studies involving quantum materials and low-dimensional systems are surveyed from the standpoints of dynamical mechanisms and basic symmetries, highlighting interplays between intrinsic and designer structuring.
Quantitative phase imaging (QPI) has emerged as method especially for investigating biological specimen. However, conventional methods often suffer from shortcomings in image quality, such as the twin image artifact of inline holography. The presented compact 3D sensing system utilizes a novel computational framework for QPI from single intensity images. The reported system offers accurate and efficient 3D profiling, overcoming the limitations of conventional inline holography approaches. This paradigm shift is promising for biomedical imaging, and material analysis.
