Abstract
In one embodiment, a package includes: a substrate; a photonic integrated circuit (PIC) adapted to the substrate, the PIC including at least one optical circuit, a first plurality of waveguides, a second plurality of waveguides, and a laser to output optical energy via the first plurality of waveguides; and a prism assembly adapted to the substrate to reflect the optical energy output from the first plurality of waveguides to the second plurality of waveguides, the prism assembly including a prism and at least one isolator. Other embodiments are described and claimed.

An apparatus comprising:
- a package having:
- a substrate;
- a photonic integrated circuit (PIC) adapted to the substrate, the PIC including at least one optical circuit, a first plurality of waveguides, a second plurality of waveguides, and a laser to output optical energy via the first plurality of waveguides;
- and
- a prism assembly adapted to the substrate to reflect the optical energy output from the first plurality of waveguides to the second plurality of waveguides, the prism assembly including a prism and at least one isolator.
A method comprising:
- outputting light generated in a laser of a photonic integrated circuit (PIC) from the PIC;
- directing the light through a first lens adapted to the PIC to a retroreflector adjacent the PIC;
- receiving the light from the retroflector in the PIC, the light isolated via the retroreflector;
- and
- using the light in an optical circuit of the PIC.
A system comprising:
- a package comprising:
- a photonic integrated circuit (PIC) having at least one optical circuit, a first region having a first plurality of waveguides, a second region having a second plurality of waveguides, and at least one laser to output optical energy via the first plurality of waveguides;
- an isolator adjacent to the first region of the PIC, the isolator to isolate the optical energy communicated through the first plurality of waveguides;
- and
- a retroreflector prism adjacent to the isolator, the retroreflector prism to reflect the optical energy output from the first plurality of waveguides to the second plurality of waveguides;
- and
- at least one processor coupled to the package.
