Abstract
Multichannel optical assemblies for optical IO (input output) systems are provided. The optical assemblies comprise an optical isolator. In some examples the optical assemblies also comprise an array of GRIN lenses. In other examples, the optical assemblies also comprise micromirrors.
Claims20
An optical assembly comprising:
- an optical isolator;
- at least two gradient index (GRIN) lens arrays wherein a first GRIN lens array is an input lens for the optical isolator and a second GRIN lens array is an output lens for the optical isolator;
- at least two fiber arrays wherein a first fiber array is optically coupled to the first GRIN lens array and a second fiber array is optically coupled to the second GRIN lens array;
- and
- a housing wherein the housing comprises first, second, third, and fourth arrays of grooves and wherein fibers of the first fiber array are in the first array of grooves, the fibers of the second array of fibers are in the second array of grooves;
- wherein the first GRIN lens array is in the third array of grooves, wherein the second GRIN lens array is in the fourth array of grooves, and wherein the first array of grooves, the second array of grooves, and the third array of grooves, and the fourth array of grooves are not contiguous with each other.
