Towards ultracompact photonic chips using higher-order modes in closely spaced waveguides
Fahmy Yousry, Panu Hildén, Radoslaw Kolkowski +1
Photonic integrated circuits are gaining traction in the field of telecommunications and information processing for their low-loss and high-throughput data transmission in comparis…
Exact electromagnetic multipole expansion using elementary current multipoles
Radoslaw Kolkowski, Sagar Sehrawat, Andriy Shevchenko
Multipole expansion plays an important role in the description of electromagnetic scatterers, allowing them to be accurately characterized by a small set of expansion coefficients.…
Spatial Filtering with Nonlocal Non-Hermitian Metasurfaces
Biao Chen, Mikael Reichler, Radoslaw Kolkowski +1
Spatial filtering of optical fields has widespread applications ranging from beam shaping to optical information processing. However, conventional spatial filters are bulky and ali…
Enhanced factor and robustness of photonic bound states in the continuum merging at locally bent trajectories
Huayu Bai, Andriy Shevchenko, Radoslaw Kolkowski
Bound states in the continuum (BICs) in planar photonic structures have attracted broad scientific interest owing to their exceptional capability to confine light. Topological robu…
