In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported a photopumped lasing from a buried dielectric photonic ...

Their findings, published in IEEE Photonics Journal, improve upon current laser design and open new avenues for defense applications.

Cylindrical vector beams have spawned numerous applications in modern optics. Although cylindrical vector pulses with several tens of megahertz repetition rate can be obtained directly at the laser ...

In this paper, we consider a beamforming vector design and device selection problem in over-the-air computation (AirComp) for federated learning. Since the learning performance improves as more ...
