A new technical paper titled “Advances in waveguide to waveguide couplers for 3D integrated photonic packaging” was published ...

Silicon photonic grating couplers represent a pivotal element in the integration of optical devices onto chips. They serve as the interface between optical fibres and on-chip waveguides, enabling ...

Figure 1 Schematic diagram of a three-dimensional integrated multichannel waveguide grating filter: (a) 1:1 planar beam splitter, (b) 1:1 three-dimensional beam splitter, (c) waveguide gratings ...

Researchers have succeeded in making the thinnest ever optical device in the form of a waveguide just three atomic layers thick. The device could lead to the development of higher density ...

IBM has created low-loss (0.3% loss over 10 microns) silicon waveguide could enable new photonic chip designs for applications that rely on visible light, and could lead to more efficient lasers and ...
