With the ever-increasing demand for more complex functionalities and miniaturization of photonic devices, the design of such devices requires a whole new different approach, deviating from classical photonic design approaches. Conventionally, the design of a typical photonic device starts with a prior knowledge, intuition, and practical experience of specific behavior...
Computer systems supported by photonic interconnects and photonic memory devices can reach performance and energy efficiency levels unattainable through purely electronic means across scales, from processor chips to the data center. However, the promised benefits cannot be realized through a simple replacement process; to reach their full potential, several aspects...
Miniaturized lasers are important for fundamental studies of light-matter interactions and applications in on-chip photonic integration. Plasmonic nanoparticle lattices supporting surface lattice resonances can provide optical feedback for directional lasing emission at room temperature. This thesis focuses on how the design of plasmon cavities can enable engineering of laser emission...
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...
Patterning hierarchical structures in three-dimension (3D) has created nature-inspired functional surfaces. Gecko feet structures have been mimicked for reversible adhesive properties, shark skin for reduced drag, and lotus leaves for self-cleaning surfaces. Rational design of out-of-plane patterns across multiple length scales is crucial because each micro- and nano-feature has different...
