This thesis investigates the potential of flat optics as a solution to the problem
of bulky and expensive optical components in producing lightweight and
wearable optoelectronic devices. The research addresses scalability challenges
in structure fabrication, design of broadband operating devices, and increasing
operational and transmission efficiency in the visible range. It focuses
on the experimental part of the challenge. The study evaluates various design
approaches, including inverse designs using optimization techniques as
well as the use of machine learning algorithms. The thesis aims to explore a
path toward high efficiency, wide bandwidth, functional response, and scalable
fabrication in flat optics using semiconductor nanostructures. The results
demonstrate the potential of using semiconductor nanostructures to engineer
efficient, scalable, and broadband optical components in obtain light processing
through flat surfaces.
