Controlling light at the micro- and nanoscale opens up opportunities for a better understanding of the world and the development of technology. As modern electronics approaches the limits of its ...

Abstract: In this paper, we propose and validate a new approach for increasing the optical bandwidth of waveguide grating couplers by using a center-symmetric grating structure. Our results ...

Introduction:Attosecond pulses capture ultrafast electron and light–matter dynamics on the shortest timescales accessible to controlled experiments ...

Abstract: Ensuring adequate wireless coverage in upcoming communication technologies such as 6G is expected to be challenging. This is because user demands of higher data rate require an increase in ...
