We show that the mode strengths of a guided field in an arbitrary asymmetric channel waveguide can be uniquely determined from self-referencing interferometric measurements at the exit plane of the ...

Guiding light is an essential task in optics, from optical fibres to compact nanoscale systems. Here, a few-atoms-thin MoTe 2 layer embedded into a planar waveguide emits photons into waveguide modes ...

Augmented reality (AR), the technology that overlays digital content onto what users see around them in real-time, is now widely used in the retail, gaming and entertainment industries, as well as in ...
