Electromagnetic (EM) waveguides are ubiquitous devices in spacecraft, naval, electrical, and communication systems to deliver microwave energy from their inlets to outlets 1. Most EM waveguides are ...
Rectangular waveguide is the most common type of transmission line used in microwave communication. It is a metallic transmission line ideally suitable for microwave frequencies and is employed to ...
Holographic images: the two figures on the left are two holographic images produced by a leaky-wave metasurface at two different distances from the device surface. The other figures are distinct ...
Photonics integrated circuitry would benefit considerably from the ability to arbitrarily control waveguide cross-sections with high precision and low loss, in order to provide more degrees of freedom ...
Holographic photopolymers can be cast onto and around other optical elements, then patterned with a 3D routed waveguide to form hybrid integrated photonics. While multi-photon initiation can be used ...
A team of Columbia Engineering researchers, led by Applied Physics Assistant Professor Nanfang Yu, has invented a method to control light propagating in confined pathways, or waveguides, with high ...
Researchers have now developed a new superior hardware platform for artificial intelligence accelerators using photonic integrated circuits on silicon chip. Co-packaged optics (CPO) technology can ...
