  • Feb 2021
A novel design has been approached for subwavelength grating sensor that operates on differential transmission. Device has been analyzed on finite difference time domain method and characterized as a biosensor that has a sensitivity value of 0.04786/nm, with a less than 0.1 nm limit of detection, on a compact scalable silicon photonic waveguide.

  • May 2021
A wide variety of nanophotonic applications require controlling the optical phase without changing optical absorption, which in silicon (Si) photonics has been mostly pursued electrically. Here, we investigate the unique light–matter interaction exhibited by epsilon-near-zero (ENZ) materials for all-optical phase control in nanophotonic silicon wav...
