Partial Confinement Photonic Crystal Waveguides: A Design Scheme for Light Guiding in a Deep-Via Etch for an IC Chip/Optical Network Bi-Directional Transceiver
Invention type: Technology
/
Case number: #11826
An optical waveguide structure includes an air-via region that receives an optical signal from an optical source. A photonic crystal cladding region is formed on the surface of the air-via region. The photonic crystal cladding region confines the optical signal within the air-via region and propagates the optical signal along the axial direction while ensuring near complete transmission of the optical signal.
