Fused Vertical Couplers

The new UC technology enables the development of compact and scalable 3-D directional couplers (by allowing vertical separation of input and output waveguides), and solves some of the problems in optical switching. B. Liu, A. Shakouri, P. Abraham, B. Kim, A. W. Jackson, and J. E. Bowers, "Fused Vertical Couplers," Applied Physics Letters 72(21): 2637-2638 (1998).

The vertical coupler provides multilevel capabilities of importance to the entire optoelectronics industry.

Using wafer fusion, scientists at the University of California have fabricated a novel vertical-directional coupler with a very short coupling length (47 micrometers).
