Room: ECE202
          The exponential growth of internet traffic continues
unabated with proliferation of bandwidth-hogging applications and
mobile devices.  The speed at which the data traffic has been
increasing has outstripped the pace of Moore’s law and is beginning to
challenge the optical transport capacity, which until quite recently
was considered abundant and cheap.  Lately, the strategy to increase
the optical transport capacity has centered on more efficient use of
easily available optical spectrum by using complex multi-level
modulation formats, as the available optical wavelengths become fully
lit.  At the same time, the fiber optical communication is becoming
more computationally intensive as it is beginning to rely on coherent
reception and computational penalty mitigation.  This reliance on
high-speed electronic signal processing poses two significant
challenges, which are increased energy consumption and network
latency.  Signal processing in the optical domain, especially using
compact photonic integrated devices, is an alternative that can offer
substantial reduction in energy consumption with increased processing
speed.   In this talk, I will present my recent activities supporting
all-optical signal processing and photonic integration in
fiber-optical communication.
Dr. Inuk Kang is a Principal Optical Investigator at LGS Innovations.
He received his Ph. D. in Physics (1997) from Cornell University.
Prior to joining LGS Innovations in 2013, Dr. Kang was an Associate
Professor at Seoul National University in South Korea.  From
2000-2012, he was a Member of Technical Staff at Bell Labs in Holmdel,
New Jersey. He is a Fellow of Optical Society of America and served as
an Associate Editor for Optics Express from 2008-2014.  He has over
100 publications and 15 patents in the areas of integrated photonics
and fiber optical communication.  His current research interests
include photonic signal processing, integrated optics, high-power
lasers and amplifiers, and quantum information.
