            widely recognized as the world's most significant
            conference and this is also the world's largest exhibit on
            lasers and electro-optics in North America. Dr. Chiao's
            presentation is part of the CLEO/QELS Lasers and
            Electro-Optics Applications Program (LEAP), which presents
            a distinguished group of speakers who explore technology
            and business areas in fiber optics and photonics. The
            CLEO/QELS conference is managed by the Optical Society of
            America.
