Femtosecond Pulse Shaping by Metasurfaces

Name: Work Video:
Duration: 3 min 30 s
Description: Metasurfaces provide extremely fine spatial control over the amplitude and phase of incident light. Here, we demonstrate shaping of <15 femtosecond ultrafast laser pulses using a silicon-metasurface acting as both spectral amplitude and phase mask.
