Paper Abstract

We review recent progress on developing passive subwavelength grating (SWG) waveguide devices in silicon photonics (SiP), including optical filters based on Bragg structures, ring resonators, and contra-directional couplers. We also discuss how to use SWG structures to implement an index variable optical true time delay line based on spatial diversity with an equal length waveguide array. These components expand significantly the SiP SWG waveguide ‘toolbox’ thereby enabling the design and implementation of more complex devices for advanced signal processing and filtering.
