Claims23
An opto-electronic package facilitating the passive alignment of VCSELs to waveguides;
- said package comprising:
- a core bearing a first surface;
- a first cladding layer positioned on said first surface of said core;
- a contact pad positioned on at least a position of the surface of said first cladding layer;
- a second cladding layer located on a further surface position of said first cladding layer;
- a waveguide channel being positioned in said second cladding layer;
- and
- optical means being in optical communication with said waveguide channel in said second cladding layer and in electrical connection with said contact pad on said first cladding layer.
A method of producing an opto-electronic package facilitating the passive alignment of VCSELs to waveguides;
- said method comprising:
- providing a core having a first surface;
- positioning a first cladding layer on said first surface of said core;
- arranging a contact pad on at least a portion of the surface of said first cladding layer;
- locating a second cladding layer on a further surface portion of said first cladding layer;
- positioning a waveguide channel in said second cladding layer;
- and
- providing optical means in optical communication with said waveguide channel in said second cladding layer and in electrical connection with said contact pad on said first cladding layer.
An opto-electronic package for alignment of a VCSEL to a waveguide, said package comprising:
- a first dielectric layer;
- a first signal conductor on said first dielectric layer;
- a second dielectric layer overlying said first signal conductor and exposed portions of said first dielectric layer;
- an optical waveguide within and parallel to said second dielectric layer;
- a third dielectric layer on said second dielectric layer for mounting an optical device;
- and wherein:
- there is an opening through said third dielectric layer to permit an optical path between said optical device and said waveguide;
- and
- there is an opening through said second and third dielectric layers to permit an electrical connection of said optical device to said first signal conductor.
