Great work! Here's some prior art in the (torch) space: https://github.com/vccimaging/DiffOptics A few notes, though paraxial approximations are "dumb", they are very useful tools for lens designers and

I received my PhD in applied physics and had colleagues, collaborators, and some published work in this (very broad) field. Although I'm familiar with the programs, my advice is not specific. The question you have to answer first is: w

> They may use absorbing substrate, or may add a backside coating. Yup, since the optic is planar it can integrate with backend coating processes > Contact image sensors ... No clue how this relates to meta-lenses. I'm also not s

We (metalenz.com) use Julia extensively in our optical design/simulation/modeling workflows: 1. Design team keeps live sessions during interactive work, otherwise launches on virtualized servers (and things take sufficiently long

Ah, that's too bad, but I can't really blame them. Going from a fully-featured Python codebase they already had in https://github.com/brandondube/prysm and translating into Julia would need to be motivated by

I was mostly referring to the parent comment's suggestion that low level numerical libraries wouldn't benefit from a pure Julia implementation, specifically to the statement that it was still better to write optimized C/FORTR

There is a recent effort [1] to provide low-level support for faster operations by transforming user code to take advantage of a compiler's instruction set, memory packing, etc. This is being expanded upon to essentially provide a Juli
