Classification: CPC G | IPC G

Claim 6:
7. 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,
the PIC chip and the WG chip are mounted on a first surface of a substrate, and
a bottom surface of the WG chip comprises an array of solder bumps configured to align with an array of solder bumps provided on the first surface of the substrate.
