H.Y.Choi won BSPA
Hyun-Young Choi, Doctor’s course at the Lightwave Systems Research Laboratory (LSRL) of Department of Electrical Engineering of KAIST (Professor in charge Yoonchul Jung), won the Best Student Paper Awards (BSPA) in the Asia-Pacific Optical Communications 2006.
BSPA is awarded to the most prospective paper in the field of Optical Transmission, Switching, and Subsystems. Choi suggested an OSNR monitoring technique among performance monitoring techniques for the efficient maintenance and management of optical network in her paper. Her technique is based on a polarization-nulling method using the polarization features of optical signals. It employs polarization mode dispersion compensator and acousto optic tunable filter (AOTF) to prevent monitoring errors arising from polarization mode dispersion (PMD) and non-linear double refraction, which considerably improves the monitoring technique and makes it possible to demonstrate a technique proposed at ultra long haul network.
