Abstract

The novel property of optical meta-devices, which consist of meta-antenna made by artificial nanostructures, has recently attracted lots of attention. The significant advantages of meta-devices are their new functionalities, lighter weight, small size, high efficiency, better performance, broadband operation, lower energy consumption, and CMOS compatibility for mass production. Given the demand for photonics, optical meta-devices for the application and control of incident light are being quickly developed for beam deflection and reflection, polarization control and analysis, holography, second-harmonic generation, laser, tunability, imaging, absorption, color display, focusing of light, multiplex color routing, and light-field sensing. Here we experimentally demonstrated the optical meta-devices in bio-photonics. We report three applications, varifocal Moiré meta-lens, meta-lens-based light-sheet fluorescent microscopy, and abrupt autofocusing meta-lens. We showed three optical meta-devices for bio-imaging, including varifocal, light-sheet, and abrupt autofocusing beams. Optical meta-devices have become a novel technique for in vivo imaging in cell biology research.
