Abstract: We present design of plasmonic modulators using vanadium dioxide (VO 2) as modulating material realized on silicon-on-insulator (SOI) wafer with only 200 nm × 140 nm modulating section ...

Segmenting silicon waveguides at the subwavelength scale produce an equivalent homogenous material. The geometry of the waveguide segments provides precise control over modal confinement, effective ...

Scientists are designing a new living material that captures carbon dioxide directly from the air. It uses photosynthetic ...
