Abstract:
An optical coupling structure is provided, an exemplary structure has a single-mode polymer waveguide terminated with a lens-shaped coupling structure on each end between an edge emitting laser chip and a single mode fiber. The edge emitting laser is assembled on the lower cladding layer of the waveguide front end with a gap filled with index matching structure, with multiple layers of different index materials for better matching efficiency. Another exemplary structure is a multiple channel polymer waveguide, developed for transmitting optical signals from edge emitting laser arrays to fiber arrays as well as to receive optical signals from fiber array to photodiode arrays. The multiple channel polymer waveguides are assembled with multiple channel connector to link to fiber cable. Multiple channel polymer waveguide cores are made to form angles with waveguide axial direction to compensate for the pitch difference between edge emitting laser channels and the single mode fibers in the fiber cable.

Claim (Index 17):
A multiple channel optical coupling structure comprising:\n a plurality of laser diodes; a multiple channel polymer waveguide comprising a plurality of core structures made of a first polymer and a cladding structure made of a second polymer, a first end, a second end, and a plurality of first integrally formed lenses at the first end, wherein the plurality of laser diodes each is aligned with one of the plurality of first integrally formed lenses: a multiple channel connector aligned with the second end of the multiple channel polymer waveguide; and a plurality of single mode optical fibers assembled in a fiber cable and aligned with the multiple channel connector; wherein the plurality of core structures in the multiple channel polymer waveguide is arranged to form a plurality of angles with a waveguide axial line to compensate a pitch difference between laser channels and the single mode optical fibers in the fiber cable, wherein the plurality of angles is a multiple of \u03b8 (\u03b8=pitch difference/waveguide length).
