Spectrally smooth broadband response via autocorrelation-constrained inverse design
Johannes Gedeon, Rasmus E. Christiansen, Rasmus Ellebæk Christiansen +1
Time-domain inverse design in photonics is known to be suitable for maximizing the efficiency of optical devices over broad frequency ranges. Objectives commonly used in this conte…
Efficient first-principles inverse design of nanolasers
Beñat Martinez de Aguirre Jokisch, Alexander Cerjan, Rasmus Ellebæk Christiansen +3
We develop and demonstrate a first-principles approach, based on the nonlinear Maxwell-Bloch equations and steady-state ab-initio laser theory (SALT), for inverse design of nanostr…
Orders-of-magnitude reduction in photonic mode volume by nano-sculpting
Rasmus E. Christiansen, Jesper Mørk, Ole Sigmund
Achieving strong light-matter interaction is important for studying and exploiting several physics phenomena. The light-matter interaction strength depends on the optical field int…
Engineering optical forces through Maxwell stress tensor inverse design
Beñat Martinez de Aguirre Jokisch, Rasmus Ellebæk Christiansen, Ole Sigmund
Precise spatial manipulation of particles via optical forces is essential in many research areas, ranging from biophysics to atomic physics. Central to this effort is the challenge…
On performance bounds for topology optimization
Anna Dalklint, Rasmus E. Christiansen, Ole Sigmund
Topology optimization has matured to become a powerful engineering design tool that is capable of designing extraordinary structures and materials taking into account various physi…
