Are this metalens probably fabricated similar to DTI or MEMS structures? like described here: https://en.wikipedia.org/wiki/Deep_reactive-ion_etching#Bosch_process<br />if it is etched the cost should be quite low, similar process steps happen many times for e.g. every image sensor with DTIAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-69244206866339320162021-12-20T17:27:12.897+02:002021-12-20T17:27:12.897+02:00There have been some interesting metalens designs ...There have been some interesting metalens designs published so far. This one falls into the waveguide category that features quite long nanopost with high index and modulate phase shift by horizontal dimension. I am curious about the cost of manufacturing such metalens and how is the yield rate if any.Anonymousnoreply@blogger.com
