Abstract:
Embodiments herein describe a photonic chip which includes a coupling interface for evanescently coupling the chip to a waveguide on an external substrate. In one embodiment, the photonic chip includes a tapered waveguide that aligns with a tapered waveguide on the external substrate. The respective tapers of the two waveguides are inverted such that as the width of the waveguide in the photonic chip decreases, the width of the waveguide on the external substrate increases. In one embodiment, these two waveguides form an adiabatic structure where the optical signal transfers between the waveguides with minimal or no coupling of the optical signal to other non-intended modes. Using the two waveguides, optical signals can be transmitted between the photonic chip and the external substrate.

Claim (Index 2):
The optical system of  claim 1 , wherein the photonic chip further comprises:\n an optical via disposed between the evanescent coupler and the silicon waveguide, wherein the optical via includes a plurality of waveguides disposed at different layers spaced apart along the direction normal to the active surface layer, and wherein portions of the plurality of waveguides are tapered to transfer optical signals between the evanescent coupler and the silicon waveguide.
