Diamond nanophotonics

We demonstrate the coupling of single color centers in diamond to plasmonic and dielectric photonic structures to realize novel nanophotonic devices. Nanometer spatial control in the creation of single color centers in diamond is achieved by implantation of nitrogen atoms through high-aspect-ratio channels in a mica mask. Enhanced broadband single-photon emission is demonstrated by coupling nit...

Nanophotonics for Lab-on-Chip Applications

Optical methods are the preferred measurement techniques for biosensors and lab-on-chip applications. Their key properties are sensitivity, selectivity and robustness. To simplify the systems and their operation, it is desirable to employ label-free optical methods, requiring the functionalization of interfaces. Evanescent electromagnetic waves are probing the optical properties near the interf...

Femtosecond Nanophotonics and Microscopy

Two-Dimensional Material Nanophotonics

The emerging two-dimensional (2D) materials exhibit a wide range of electronic properties, ranging from insulating hexagonal boron nitride (hBN), semiconducting transition metal dichalcogenides (TMDCs) such as molybdenum disulfide (MoS2) and tungsten diselenide (WSe2), to semi-metallic graphene. The plethora of 2D materials together with their heterostructures, which are free of the traditional...
