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 10):
A photonic chip, comprising:\n an active surface layer comprising a first optical component optically coupled to a silicon waveguide; an evanescent coupler spaced apart from the silicon waveguide along a direction normal to the active surface layer, wherein the evanescent coupler is optically coupled to the silicon waveguide; and a coupling interface parallel to the active surface layer, wherein the evanescent coupler is arranged proximate to the coupling interface to permit the evanescent coupler to optically couple to an external optical device when the external optical device is bonded to the coupling interface.
