Abstract

A novel electro-opto-mechanical assembly is provided. The electro-opto-mechanical assembly comprising: a first wafer, the wafer having a top and bottom surface; at least one optical element disposed on one surface of the first wafer; at least one discrete opto-electronic transducer element disposed on the bottom surface of the first wafer and in optical communication with the optical element; and an optical waveguide; wherein the first wafer and the optical element form an optical relay which relays light between the discrete opto-electronic transducer and the optical waveguide and thereby forms an efficient optical coupling between the discrete opto-electronic transducer and the optical waveguide.

Claims (16)

1. An optical wafer comprising:

one or more refractive lenses, each of said refractive lenses being comprised of molded plastic and including a first surface having a radius of curvature of 300 micrometers or less; and

an alignment means for aligning said one or more refractive lenses with one or more respective optical fibers, said alignment means being integral with said one or more refractive lenses.

2. The optical wafer of claim 1 , wherein said alignment means comprises a passive alignment feature.

3. The optical wafer of claim 1 , wherein said alignment means comprises one or more pins.

4. The optical wafer of claim 1 , wherein said alignment means comprises one or more receptacles.

5. The optical wafer of claim 1 , wherein said optical wafer comprises at least two refractive lenses.

6. The optical wafer of claim 1 , wherein said optical wafer comprises a one-dimensional array of refractive lenses.

7. The optical wafer of claim 1 , wherein said optical wafer comprises a 1×12 array of refractive lenses.

8. The optical wafer of claim 1 , wherein said optical wafer comprises a two-dimensional array of refractive lenses.

9. A molded plastic optical wafer comprising:

an array of two or more refractive lenses, each of said refractive lenses including a first surface having a radius of curvature of 300 micrometers or less; and

one or more alignment pins for aligning each of said refractive lenses with a respective optical fiber of an array of optical fibers.

10. A molded plastic optical wafer comprising:

a one-dimensional array of refractive lenses, each of said refractive lenses including a first surface having a radius of curvature of 300 micrometers or less; and

two alignment pins for aligning said array of refractive lenses with an array of optical fibers.
