Abstract
Via electrochemical etching of silicon, various nanophotonic elements, including flat lenses, photonic nanojet generators, Bragg mirrors, polarization sensitive optical splitters and structures with nearly arbitrary refractive index distributions were formed. The conversion from silicon to silica and titania enabled the optics to operate in the visible with minimal loss, something particularly important for visible light applications. A detailed model was developed which enabled tight control over optical properties based only on the electrochemical etch conditions.
