Light collection efficiency is an important factor that affects the performance of many optical and optoelectronic devices. In these devices, the high reflectivity of interfaces can hinder efficient ...

The Federal Communications Commission is weighing whether to grant Reflect Orbital, a startup proposing to bounce sunlight back to Earth after dark, the authority to launch and operate an experimental ...

Light propagation is usually reciprocal meaning that the trajectory of light travelling in one direction is identical from that in the opposite direction. Breaking reciprocity can make light propagate ...

The Federal Communications Commission is reviewing a proposal from Reflect Orbital, a startup that wants to place mirror-equipped satellites in orbit to bounce sunlight back to Earth after dark. The ...

Introduction Can you imagine a bouncy ball that could bounce back and forth between two walls, infinitely—that is, forever? Wouldn't that be amazing? What if, instead of a ball, light was bouncing ...

The development of clean and low-cost solar photovoltaic technology is crucial for the global transition toward carbon ...
