Structured light engineering using a photonic nanojet
Maryam Yousefi, Daniel Necesal, Toralf Scharf +1
In this letter, we present the photonic nanojet as a phenomenon in a structured light generator system that is implemented to modify the source focal spot size and emission angle.…
Adjoint method and inverse design for diffractive beam splitters
Dong Cheon Kim, Andreas Hermerschmidt, Pavel Dyachenko +1
Diffractive optical elements with a large diffraction angle require feature sizes down to sub-wavelength dimensions, which require a rigorous electromagnetic computational model fo…
Using effective medium theories to design tailored nanocomposite materials for optical systems
Daniel Werdehausen, Isabelle Staude, Sven Burger +4
Modern optical systems are subject to very restrictive performance, size and cost requirements. Especially in portable systems size often is the most important factor, which necess…
Design rules for customizable optical materials based on nanocomposites
Daniel Werdehausen, Isabelle Staude, Sven Burger +4
Nanocomposites with tailored optical properties can provide a new degree of freedom for optical design. However, despite their potential these materials remain unused in bulk appli…
Limit of light coupling strength in solar cells
A. Naqavi, F. -J. Haug, C. Ballif +2
We introduce a limit for the strength of coupling light into the modes of solar cells. This limit depends on both a cell's thickness and its modal properties. For a cell with refra…
Angular behavior of the absorption limit in thin film silicon solar cells
Ali Naqavi, Franz-Josef Haug, Karin Söderström +5
We investigate the angular behavior of the upper bound of absorption provided by the guided modes in thin film solar cells. We show that the 4n^2 limit can be potentially exceeded…
