Single freeform surface design for prescribed input wavefront and target irradiance
Christoph Bösel, Herbert Gross
In beam shaping applications, the minimization of the number of necessary optical elements for the beam shaping process can benefit the compactness of the optical system and reduce…
Ray mapping approach in double freeform surface design for collimated beam shaping beyond the paraxial approximation
Christoph Bösel, Norman G. Worku, Herbert Gross
Numerous applications require the simultaneous redistribution of the irradiance and phase of a laser beam. The beam shape is thereby determined by the respective application. An el…
Ray mapping approach for the efficient design of continuous freeform surfaces
Christoph Bösel, Herbert Gross
The efficient design of continuous freeform surfaces, which transform a given source into an arbitrary target intensity, remains a challenging problem. A popular approach are ray-m…
Nonlocal effects: relevance for the spontaneous emission rates of quantum emitters coupled to plasmonic structures
Robert Filter, Christoph Bösel, Giuseppe Toscano +2
The spontaneous emission rate of dipole emitters close to plasmonic dimers are theoretically studied within a nonlocal hydrodynamic model. A nonlocal model has to be used since qua…
