Abstract:
A fiber alignment or “fiberposer” device enables the passive alignment of one or more optical fibers to a photonic integrated circuit (PIC) device using mating hard-stop features etched into the two devices. Accordingly, fiber grooves can be provide separate from the electrical and optical elements, and attached to the PIC with sub-micron accuracy. Fiberposers may also include a hermetic seal for a laser or other device on the PIC. All of these features significantly reduce the typical cost of an actively aligned optical device sealed in an hermetic package.

Claim (Index 33):
A method of aligning an optical fiber to a waveguide on a photonic optical chip (PIC) comprising:\n providing an optical fiber alignment device for aligning an optical fiber with an optical waveguide on a photonic integrated circuit (PIC) comprising:\n a base; \n a groove in said base for receiving a portion of the optical fiber, whereby a core of the optical fiber is aligned with a core of the optical waveguide of the PIC; \n first alignment features; \n providing the PIC, comprising:\n a substrate; \n an electronic or opto-electronic component mounted on the substrate; \n the optical waveguide in an optical waveguide layer mounted on the substrate; \n second alignment features for abutting with the first alignment features; \n mounting the optical fiber alignment device on the PIC with the first alignment features aligned with the corresponding second alignment features; aligning the optical fiber with the optical waveguide; and fixing the optical fiber alignment device to the PIC.
