ABSTRACT:
A flexible optical coupler for coupling light signals from an optical waveguide on a circuit board or substrate to an optical waveguide on another circuit board or substrate, or to an optical port on an electronic, opto-electronic or photonic integrated circuit. The coupler is self-aligning by virtue of the design of the alignment stops fabricated in close proximity to the optical waveguide or optical port. The coupler may consist of an array of optical waveguides between an array of optical ports and another array of optical ports. The coupler may be used with any substrates appropriate for polymeric waveguide fabrication, including many circuit board materials. The optical waveguide of the coupler is on a flexible and transparent substrate. The coupler is effective for optical connections between devices situated on noncoincident surfaces. Alignment stops are utilized for the case of aligning the ports of the optical coupler to other ports. Alignment stop fabrication is not restricted to crystallographic etch processes.
