* Beam shaping optics are important for improving laser manufacturing, optical sensor performance, Time-of-Flight (TOF) depth sensing
* Beam shaping optics need:
1) Control output light shape
2) Single component (robust + lower cost)
3)Robust / High damage threshold (laser manufacturing)
PlanOpSims task was to design a metasurface top-hat beam shaper for an incident Gaussian beam
Specifications
1) Input beam: 500ðœ‡ð‘š Gaussian beam with focus plane on metacomponent
2) Output: 500ðœ‡ð‘š wide square top-hat imaged at 5mm behind metacomponent*
Meta surface design
1) Meta-atom optimization PlanOpSim meta-cell software ð‘†ð‘–ð‘‚2 + ð‘‡ð‘–ð‘‚2 pillars
2) Meta-surface wavefront shaping & analysis simulation
