One of the very important reasons for this is its weak anti-interference capability and poor stability. Conventional methods to prepare terahertz phase modulators are very sensitive to material defects and physical bending. Recently, a terahertz chip with topological photonics has been effectively solved...
AMES, Iowa, March 4, 2020 — Some topological materials are insulators in their bulk form but possess electron-conducting behavior on their surfaces. The contrast in the behavior of these surface electrons is promising for future applications but challenging to control. Uncontrolled interactions ...
Like in an optical fiber, the 1550 nm wave is guided along the waveguide that is fed by a (sometimes lensed) fiber at the chip’s edge. When the light arrives at the terahertz diode that is mounted on top of the waveguide, the high refractive index of the diode (the refractive ...
Here, inspired by phyllotaxis patterns in pine cones and sunflowers, we theoretically prove and experimentally report that multiple optical vortices can be produced in a single compact phyllotaxis nanosieve, both in free space and on a chip, where one meta-atom may contribute to many vortices ...
Despite the high-speed computation and parallel processing capabilities of space-diffractive neural networks, the THz SPNN offers easier integration, higher transmission efficiency, and the capability for on-chip communication fabrication. In comparison to planar diffractive networks, the THz SPNN achieves ...
This paper presents an on-chip device that can perform gigahertz-rate amplitude modulation and switching of broadband terahertz electromagnetic waves. The operation of the device is based on the interaction of confined THz waves in a novel slot waveguide with an electronically tunable two dimensional ...
