Arrayed waveguide gratings (AWGs) are planar optical devices that disperse and multiplex multiple wavelengths of light by exploiting phased-array interference. In integrated photonics, AWGs serve as ...

As we know, DWDM technology enables transmission of dozens of wavelengths in a single fiber, which expands the capacity of optical fiber communication enormously. The first mux/demux modules for DWDM ...

Optical technology harnesses the properties of light—its coherence, intensity and phase—to develop devices and systems for sensing, imaging, communication and navigation. Recent advances in integrated ...

What are modal effects? Integrated photonics—the devices and the materials used to make them happen. One of the key planar-waveguide configurations: the ring resonator. The roots of waveguide optics ...
