Ongoing UROP utilising the NanoScribe 3D printer to fabricate nanostructures that interfere with light to produce desired effects.
Simulations were done using Lumerical FDTD software of colour filters by making pillars. The results show that the pillars scatter light and let certain frequencies through.
We also 3D printed structures that form pictures using the Gerchberg-Saxton Algorithm on glass. Done by hardening photoresist using lasers.
Make nice poster on a tiny 25mm glass square slide, seen only by shooting a laser through the poster. Pew pew pew pew.
Diffraction grating but cooler.
