Of course, for us Frenchies the City of Lights is the old/odd nickname of Paris. For us Entrepreneurs, Dreamers, and Danny Ocean' s fans it's also the nickname of Las Vegas.
The City Of Light (note the singular) is a book by Jeff Hecht, published in 1999 : the amazing story of Fiber Optics. The expanded table of contents is available here. Order from Barnes&Noble here.
More on Jeff himself on his own web site here. I have had the chance to meet with Jeff a couple of times in the late 90's. An exceptional writer, who puts simple words onto complex technologies.
