Researchers have built a microscopic 3D-printed optical device that funnels light from 37 separate multimode semiconductor lasers into a single optical fiber, merging 222 distinct spatial modes; the ...

Traditional wired systems have their own limitations in industrial settings. For example, conductor bars are restricted to analog signals, festoons and cable reels are limited to 330 feet for Ethernet ...

Mode Division Multiplexing (MDM) technology stands as a cornerstone for enhancing transmission capacity in fiber-optic communication systems. However, in few-mode fibers, the group velocity ...

MOE Key Laboratory of Advanced Micro-Structured Materials, Shanghai Frontiers Science Center of Digital Optics, Institute of Precision Optical Engineering, and School of Physics Science and ...

Researchers at The City College of New York have shown how a quantum emitter, the nitrogen-vacancy (NV) center in diamond, interacts in unexpected ways with a specially engineered photonic structure ...

Abstract: A novel full W-band circularly polarized (CP) horn antenna is proposed. It contains a rectangular waveguide (RWG) for feeding, a waveguide polarizer based on evanescent and propagation modes ...

For the system noise temperature calibration of the K/Q/W triple-band cryogenic receiver on Tianma Radio Telescope (TMRT), a design of W-band eight-hole waveguide directional coupler is proposed in ...

Abstract: This letter presents a novel wideband planar coplanar waveguide with ground (CPWG)-to-rectangular waveguide (RWG) transition designed for Ku-band applications. The architecture employs a ...
