Abstract :
We report the characteristics of, to our knowledge, the world´s first high efficiency generation of a so-called “non-diffracting” Bessel beam using a laser diode and a reflective holographic element. The beam has a central spot of 200 pm diameter and this spot size is maintained over a propagation distance approaching 1 meter. We consider two free-space optical interconnection schemes which take advantage of the unique characteristics of Bessel beams
