Freeform Spectrally Stable Topological Photonic Vortex Resonators
Yuma Kawaguchi, Daria Smirnova, Filipp Komissarenko +6
Topological concepts have been at the forefront of materials research in recent years, driving a revolution in our understanding of the response of quantum materials and enabling n…
Topological Pseudospin Hall Effect and Multi-frequency Corner Modes in Kagome-based Lattices
Shenglong Guo, Qinhui Jiang, Yuma Kawaguchi +2
Topological phases and modes, including pseudospin-Hall-selective edge transport and corner states, provide robust control of wave propagation and modal confinement in classical wa…
All-optical nonreciprocity due to valley polarization in transition metal dichalcogenides
Yuma Kawaguchi, Sriram Guddala, Kai Chen +3
Nonreciprocity and nonreciprocal optical devices play a vital role in modern photonic technologies by enforcing one-way propagation of light. Most nonreciprocal devices today are m…
Integrated collinear refractive index sensor with Ge PIN photodiodes
Lion Augel, Yuma Kawaguchi, Stefan Bechler +4
Refractive index sensing is a highly sensitive and label-free detection method for molecular binding events. Commercial implementations of biosensing concepts based on plasmon reso…
