Claim 0:
1. A silicon-based photonic chip comprising an interface for optically coupling the photonic chip to an optical fiber or an optical fiber assembly, wherein the interface comprises:
a single-mode waveguide configured to guide light and to provide a first light beam;
a first optical element configured to expand the first light beam in a first direction that is in-plane of the photonic chip and to confine the first light beam in a direction that is perpendicular to the plane of the photonic chip, thereby providing an expanded light beam; and
a second optical element configured to deflect the expanded light beam and to further expand the expanded light beam in a second direction that is perpendicular to the first direction, thereby providing an output light beam from the photonic chip having a beam dimension in the first direction that is the same as a beam dimension in the first direction of the expanded light beam provided by the first optical element.
