Metallacarboranes are a class of inorganic boron clusters that have recently been recognized as biologically active compounds. Herein, we report on the host–guest complexation several cobalt bis(1,2-dicarbollide) anions (COSANs) with cyclodextrins (CDs) in aqueous solution. The binding affinities reach micromolar values, which among highest known values for native CDs, and exceed those neutral hydrophobic organic guest molecules. entrapment COSANs inside cavity CDs was confirmed using NMR...
Quantum photonic devices operating in the single photon regime require detection and characterization of quantum states light. Chip-scale, waveguide-based are a key enabling technology for increasing scale complexity such systems. Collecting photons from multiple outputs at end-face chip is core task that frequently non-trivial, especially when output ports densely spaced. We demonstrate novel, inexpensive method to efficiently image route individual modes polymer chip, where undergo walk....
Abstract The effective integration of 2D materials such as monolayer transition metal dichalcogenides (TMDs) into photonic waveguides and integrated circuits is being intensely pursued due to these materials’ strong exciton‐based optical response. This work presents a platform where heterostructure (WS 2 ‐hBN) directly the mode‐center novel polymer ridge waveguide. Finite‐difference time‐domain simulations collection photoluminescence from guided mode indicate that this system exhibits...
We employ the Su-Schrieffer-Heeger model in elastic polymer waveguide arrays to design and realize travelling topologically protected modes. The observed delocalization of optical field for superluminal defect velocities agrees well with theoretical descriptions. apply mechanical strain modulate lattices' coupling coefficient.

We demonstrate boosted topological zero modes in a strain-tuneable photonic polymer waveguide array. Modulating the defect speed illustrates varying localization of light field. Theoretical predictions and experimental observation are good agreement.
2D materials such as monolayer transition metal dichalcogenides (TMDs) exhibit distinct excitonic properties that give rise to a strong and tuneable optical response [1] . Integration of TMDs' into photonic waveguides active elements is being intensely pursued. One the primary challenges maximize coupling between waveguide's mode TMD. Most solid-state platforms are limited surface placement emitter adjacent mode, where mediated only by evanescent field [2]
