Course Objectives: The recent explosive growth in the capacity and reach of wired information communication has been largely supported by key breakthroughs in the underlying lightwave systems technology. This course will focus on the fiber optic physical layer supporting the ever-growing communications infrastructure. In particular, we will cover fiber optic transmission systems including TDM, WDM, and solitons. The key phenomena including nonlinear effects that impact system performance will be examined. In the ladder part of the course we will study current optical networks. Topics covered will include wavelength routed networks, cross-connects, and optical packet switching systems.

Course Outline by Topical Areas:

Introduction, review Maxwell's equations, optical waveguides, light propagation in fibers

Pulse propagation, slowly varying envelope approximation

Group velocity dispersion, chirp, higher-order dispersion

Self phase modulation, spectral broadening

Pulse evolution with GVD and SPM, higher order nonlinear effects, experimental findings

Optical solitons, nonlinear Schrodinger equation

Four wave mixing, impact on WDM transmission

WDM components, gratings, filters

Mach-Zehnder interferometers, arrayed waveguide grating

Transmitters and signal modulation

Demodulation, ideal receiver, noise

Notes:

Before registering for Columbia classes, NTU students may contact Columbia Video Network (CVN) by e-mail at cvn@cvn.columbia.edu with any questions. ALL STUDENTS registering for a class should obtain the course syllabus, as well as download CVN's "Important Information," which includes CVN's Required Procedures, Academic Calendar, etc. available on the CVN website at http://www.cvn.columbia.edu/Registration/Information/information.html at the

beginning of the semester. This information is crucial for students to function under CVN guidelines during the course of the semester. It is the responsibility of the student to be familiar with these procedures. Course

notes, assignments, and videocassettes will be sent directly to the student, and students will be required to adhere to the course schedule for homework assignments, project due dates, and examinations. All homework assignments, projects, and exams must be sent to CVN by overnight carrier or e-mail, as described in the course syllabus. Additional Columbia requirements and procedures are explained in CVN's "Important Information" section on the web page.

Students taking this course have two viewing options: VHS videotapes ($950 additional fee domestic only) and online mode (includes both streaming lectures and downloadable lectures ($195 additional fee).

Students are highly encouraged to check our previews from http://www2.cvn.columbia.edu/preview/preview.asp. If you have technical problems, contact CVN at technical@cvn.columbia.edu.

Students should send payment by check directly to Columbia University's Accounting department (address below) in order to receive access to the course lectures:
