Low-Pass Fiber Optics to Chip Alignment



Technical Challenge:

Aligning a fiber optic cable to an integrated chip via direct coupling using current industry standards is very cumbersome, time consuming, and subject to signal loss.


This technique is a unique means to align fiber optics to a photonic integrated chip that results in lower back reflections, lower insertion losses, easier alignment, and a more rugged package. It uses a ball lens, standard single mode fiber, low index fluid, and a custom-built index photonic chip. The technique is inexpensive to implement, easily scales up to handle multiple fibers simultaneously, and blends well with automated manufacturing.

Demonstration Capability:

A demonstration is not available.

Potential Commercial Application(s):

This technology offers great benefits to manufacturers of electronic components within the information technology industry.

Patent Status:

A patent application has been filed with USPTO.

Reference Number: 1307
