Abstract
An optical system is provided. The optical system includes an optical engine having a photonic integrated circuit (PIC) and an optical lens array, the optical lens array has a lens that is optically aligned with a waveguide in the PIC. The optical system also includes an optical connector optically aligned with the optical lens array to transfer optical signals between the optical connector and the waveguide in the PIC. The optical connector includes a ferrule and an optical fiber mated with the ferrule. The ferrule has a lens aligned with the lens of the optical lens array.

An optical system, comprising:
- an optical engine having a photonic integrated circuit (PIC) and an optical lens array having a first lens that is optically aligned with a waveguide in the PIC;
- and
- an optical connector optically aligned with the optical lens array to transfer optical signals between the optical connector and the waveguide in the PIC, the optical connector comprising a ferrule and an optical fiber mated with the ferrule, the ferrule comprising a second lens aligned with the first lens, wherein the optical lens array has a fine alignment feature and the ferrule includes a fine alignment feature, the fine alignment features of both the optical lens array and the ferrule are chamfers, and wherein the chamfers are shaped complementary to one another so as to facilitate optical alignment of the second lens of the ferrule with the first lens of the optical lens array.
An optical engine, comprising:
- a lid having a support wall and a lid chamfer;
- a substrate having a substrate chamfer, the lid and the substrate defining an interior;
- a photonic integrated circuit (PIC) positioned at least in part within the interior;
- and
- an optical lens array coupled with the PIC and the support wall, the optical lens array having a first lens optically aligned with a waveguide of the PIC, and
- wherein the lid chamfer and the substrate chamfer are arranged to guide a ferrule of an optical connector toward the optical lens array and wherein the optical lens array has a chamfer arranged to guide a second lens of the ferrule into optical alignment with the first lens of the optical lens array.
An optical system, comprising:
- an optical engine having a photonic integrated circuit (PIC) and an optical lens array having a first lens that is optically aligned with a waveguide in the PIC;
- and
- an optical connector optically aligned with the optical lens array to transfer optical signals between the optical connector and the waveguide in the PIC, the optical connector comprising a ferrule and an optical fiber mated with the ferrule, the ferrule comprising a second lens aligned with the first lens, wherein the optical engine has a lid and a substrate that each include a coarse alignment feature that facilitate alignment of the ferrule relative to the optical lens array.
