The properties of nanostructured networks of conductive materials have been extensively studied under the lens of percolation theory. In this work, we introduce a novel type of local percolation phenomenon used to investigate the conduction properties of a new hybrid material that combines sparse metallic nanowire networks and fractured conducting thin films on flexible substrates. This original concept could potentially lead to the design of a novel composite transparent conducting material.

Single quantum emitters embedded in solid-state hosts are an ideal platform for realizing quantum information processors and quantum network nodes. Among the currently investigated candidates, Er^{3+} ions are particularly appealing due to their 1.5  μm optical transition in the telecom band as well as their long spin coherence times.

The Myb transcription factor is involved in the proliferation of hematopoietic cells, and deregulation of its expression can lead to cancers such as leukemia. Myb interacts with various proteins, including the histone acetyltransferases p300 and CBP. Myb binds to a small domain of p300, the KIX domain (p300), and inhibiting this interaction is a potential new drug discovery strategy in oncology.

Article Synopsis
  • Integrated wavelength filters with high optical rejection are essential for silicon photonics applications like quantum photon-pair sources and spectrometers.
  • Traditional TE-only platforms limit flexibility, but a new method combines Bragg filters with anisotropy-engineered metamaterial bends, enhancing performance.
  • This approach achieves over 60 dB optical rejection in 300-nm-thick, cladded silicon waveguides without increasing insertion loss or device size.

Waveguide Bragg grating filters with narrow bandwidths and high optical rejections are key functions for several advanced silicon photonics circuits. Here, we propose and demonstrate a new, to the best of our knowledge, Bragg grating geometry that provides a narrowband and high rejection response. It combines the advantages of subwavelength and modal engineering.
