Introduction to the event

We develop new metasurfaces and their novel applications in next generation compact optical systems. Achievements of this year includes: (1) We experimentally demonstrate the dispersion of silicon nanopillar arrays such that they temporally reshape pulses upon transmission using slow light effects and act as ultrashort laser pulse compressors. (2) We develop an achromatic flat lens to resolve the bottleneck of current AR/VR technologies using a new design principle combined with constructive coherence and dispersion-engineering. (3) We demonstrate metasurface based bijective illumination collection imaging that provides near diffraction-limited scale and maintains depth-of-focus over Rayleigh range.
