Intercalated Graphene Layers for Charge Extraction and Enhanced Light Absorption

Quantum dots (QDs) have shown extraordinary optical properties based on their size-tunable band gap and low-processing cost that have allowed the realization of promising photodetectors and solar cells. However, the short diffusion length and mobility in QD films remains a main limitation and subject of intensive research as the key to improve the performance of QD based optoelectronic devices. A very innovative strategy to overcome the low mobility of QDs is to use them as sensitizer with high conductive systems such as graphene, 2D semiconductors and Si. The combination of graphene (Gr) and QD into a hybrid device splits the photoconversion/detection “tasks” between these two complementary nanomaterials: QDs absorb light and generate photocharges, while graphene takes care of charge collection for efficient transport.

Integrated Photonic Topological Cavities For Non-Reciprocal Lasing And Cavities Of Arbitrary Shapes

Resonant cavities are essential building blocks governing many wave based phenomena, and, their geometry together with reciprocity, fundamentally limit the integration of optical devices.   Topological lasing has been proposed in two dimensions using arrays of ring resonators with no time-reversal symmetry breaking, and in one-dimensional lattice of polariton micropillars. However, these systems cannot implement cavities of arbitrary shapes due to their preserved time-reversal symmetry. An elusive, but fundamental, implication of topology is the existence of a new class of geometry-independent photonic components. For example, the possibility to construct geometry-independent cavities opens a new paradigm in cavity quantum electro dynamics and photonic integration, as, it enables denser packing of components and sources of arbitrary form-factors. This prospect will alleviate the otherwise stringent constraints to use preset cavities that leave much chip space unused. Topology also naturally addresses the pressing need for non-reciprocal components that protect sources against back scattering.
