John C. Cartledge, P.Eng.


John Cartledge received the B.Sc. degree in mathematics and engineering in 1974 and the M.Sc. and Ph.D. degrees in mathematics in 1976 and 1979, respectively, from Queen's University, Kingston, Ontario, Canada.

From 1979 to 1982, he was a Member of the Scientific Staff at Bell-Northern Research, Ottawa, where his work involved fiber-optic systems for the exchange access network and high-capacity digital radio systems. In 1982, he joined Queen's University and is currently a Professor and Queen's Research Chair with the Department of Electrical and Computer Engineering. Dr. Cartledge has spent one-year sabbatical leaves with the Lightwave Systems Technology Research Division of Bellcore, Red Bank, NJ, in 1988-89, the Optical Communications Department of Tele Danmark Research, Hørsholm, Denmark, in 1995-96, and the Optical Systems and Networks Research Department of Corning Inc., Corning, NY, in 2009-10.

Dr. Cartledge is a Fellow of the Optical Society of America, a Fellow of the Institute of Electrical and Electronics Engineers (IEEE), a former IEEE Photonics Society Distinguished Lecturer (2008-2010), and recipient of the IEEE Canada Outstanding Engineering Educator Award (2009). His conference organization activities include serving on the Technical Program Committees for the Conference on Optical Fiber Communication (1994-1997 and 2005-2006), the IEEE LEOS Annual Meeting (2002-2008), and the European Conference on Optical Communication (1997, 2006-2012). He was a Program Chair and General Chair for the Conference on Optical Fiber Communication (2008 and 2010, respectively), and a Program Chair for the IEEE Photonics Society Summer Topical Meeting (2009). He is currently an Associate Editor for IEEE Photonics Technology Letters and Editor-In-Chief for IEEE Journal of Selected Topics on Quantum Electronics..

Research Interests

Topics currently being investigated include the following:

  • clock recovery, optical regeneration and wavelength conversion using highly nonlinear fibers and semiconductor devices,
  • optical regeneration,
  • pre-compensation for spectrally efficient modulation formats,
  • pre-compensation for directly modulated lasers, and
  • signal processing for digital coherent systems.
