Abstract
Optical circuits are disclosed having a source waveguide, a first tap waveguide and a second tap waveguide. Optical power is transferred via evanescent coupling from the source waveguide to the first tap waveguide and from the first tap waveguide to the second tap waveguide such that power loss is minimized. Also disclosed are methods for fabricating optical integrated circuits.
