Low absorption in the thin active layer of conventional organic solar cells limits their power conversion efficiency. Structured surface layers are a common approach to diffracting incoming light, thus elongating its path through the active layer, th

Photonic lattices have emerged as an ideal testbed for localizing light in space. Among others, the most promising approach is based on flat band systems and their related nondiffracting compact localized states. So far, only compact localized states

The Lieb lattice and the kagome lattice, which are both well known for their Dirac cones and flat bands, can be continuously converted into each other by a shearing transformation. During this transformation, the flat band is destroyed, but the Dirac

Engineered domain structures play an essential role in nonlinear optics for quasi-phase-matched parametric processes. Pyroelectric field-assisted domain inversion with focused femtosecond laser pulses is a promising approach to create arbitrary two-d

Controlling random light is a key enabling technology that pioneered statistical imaging methods like speckle microscopy. Such low-intensity illumination is especially useful for bio-medical applications where photobleaching is crucial. Since the Ray

We report on topologically protected edge states in a four-band Lieb-like pho-tonic lattice of evanescently coupled helical waveguides. Our results demonstrate adjustable group velocities and oscillatory modal weight exchange depending on the edge te

We design and fabricate deterministic aperiodic surface structures on organic solar cells. Their diffractive properties are compared and optimized to maximize the increase of the active path length of sunlight and thus its absorption probability.

Ferroelectric domains are fabricated by patterning lithium niobate and lithium tantalate crystals with femtosecond laser pulses and subsequent heating to elevated temperatures. We investigate the role of temperature on the domain inversion process.
