Abstract
There is provided an optical module, which includes a substrate; one or more optical devices disposed on the substrate; an integrated circuit (IC) device disposed on the substrate for driving the one or more optical devices; one or more optical fibers in optical communications with the one or more optical devices, respectively; an optical bench that attaches to the substrate and concentrates a direction of the light transmitted between the one or more optical devices and the one or more optical fibers; and a cover that attaches to the optical bench with the one or more optical fibers fixed therebetween. The optical bench changes a direction of the concentrated light.
Claims20
An optical module, comprising:
- a substrate;
- one or more optical devices disposed on the substrate;
- an integrated circuit (IC) device disposed on the substrate for driving the one or more optical devices;
- one or more optical fibers in communication with the one or more optical devices, respectively;
- an optical bench that attaches to the substrate and concentrates a light transmitted between the one or more optical devices and the one or more optical fibers, wherein the optical bench changes a direction of the concentrated light;
- and
- a cover that attaches to the optical bench with the one or more optical fibers fixed therebetween,
- wherein the optical bench comprises
- a first body,
- a seating groove that is formed on a top surface of the first body to receive the one or more optical fibers, and
- an optical unit that adjoins an end of the seating groove and faces ends of the one or more optical fibers,
- wherein the optical unit concentrates and changes the direction of the light transmitted between the one or more optical devices and the one or more optical fibers;
- wherein the cover comprises
- a second body that is shaped to engage the first body of the optical bench, and
- a hold part that is formed at a bottom surface of the second body and shaped corresponding to the seating groove to hold the one or more optical fibers therebetween;
- and
- wherein a space between the seating groove and the hold part are tapered to become gradually widened from one end thereof adjoining the optical unit toward the other end portion.
