Claim 0:
1. A system integrating a fiber block and a photonic integrated circuit (PIC) chip, the system comprising:
a waveguide (WG) chip disposed between the fiber block and the PIC chip, the WG chip having a plurality of waveguides configured to transmit optical signals,
wherein:
the WG chip includes a first facet comprising a first light coupling surface providing a first light coupling with the fiber block by the plurality of waveguides and a second facet having a second light coupling surface providing a second light coupling with the PIC chip by the plurality of waveguides,
the plurality of waveguides of the WG chip are configured to be butt-coupled to waveguides embedded between upper and lower surfaces of the PIC chip at the second light coupling surface,
each of the plurality of waveguides includes a first end disposed at the first light coupling surface and a second end disposed at the second light coupling surface, and
the first ends of the plurality of waveguides are disposed at a middle of the first light coupling surface and the second ends of the plurality of waveguides are disposed at a bottom of the second light coupling surface.
