A three-dimensional polarization-insensitive grating coupler tailored for 3D nanoprinting
Oliver Kuster, Yannick Augenstein, Carsten Rockstuhl +1
Efficiently coupling light from optical fibers into photonic integrated circuits is a key step toward practical photonic devices. While a notable coupling can be achieved by out of…
Inverse-designed dispersive time-varying nanostructures
Puneet Garg, Jan David Fischbach, Aristeidis G. Lamprianidis +5
Time-varying nanostructures allow us to control the spatial and temporal properties of light. The temporal modulation of the nanostructures constitutes an additional degree of free…
Inverse Design of 3D Nanophotonic Devices with Structural Integrity Using Auxiliary Thermal Solvers
Oliver Kuster, Yannick Augenstein, Roberto Narváez Hernández +2
3D additive manufacturing enables the fabrication of nanophotonic structures with subwavelength features that control light across macroscopic scales. Gradient-based optimization o…
Inverse Design of Polaritonic Devices
Oliver Kuster, Yannick Augenstein, Carsten Rockstuhl +1
Polaritons, arising from the strong coupling between excitons and photons within microcavities, hold promise for optoelectronic and all-optical devices. They have found application…
Wide angle tolerant solar spectral splitter for lateral tandem solar cells
M. L. Schubert, J. D. Fischbach, M. Nyman +4
Maximizing the power conversion efficiency of solar cells plays a crucial role in upscaling solar energy production. Combining two or more solar cells with different bandgaps into…
Inverse-designed 3D laser nanoprinted phase masks to extend the depth of field of imaging systems
T. J. Sturges, M. Nyman, S. Kalt +5
In optical imaging, achieving high resolution often comes at the expense of a shallow depth of field. This means that when using a standard microscope, any minor movement of the ob…
