Colloidal crystals are promising candidates for nanophotonic applications due to their strong interactions with light and the capability to tailor such interactions through crystal design and engineering. DNA-programmable assembly, in particular, allows for precise structural control down to the sub-nanometer length scale. In this thesis, ways of designing, synthesizing, and...
Ultrathin optical platform including two-dimensional materials and metasurfaces have emerged as potential candidates for novel nanophotonic applications. In this dissertation, I will present the possibility to achieve full active control of the electromagnetic waves with the platform in the flatland. We could achieve the amplitude control, which will be useful...
