## Coherent and Nonlinear Lightwave CommunicationsThis is a practical source on recent developments in coherent and nonlinear lightwave communications. The book systematically presents up-to-date explanations of all the relevant physical principles and recent research in this emerging area. Providing an unparallelled engineering-level treatment (with 700 equations), this reference also describes the progression of coherent and nonlinear technology from yesterday's experimental field to today's practical applications tool. This work is intended as a tool for research telecommunication engineers, applications engineers working with broadband telecom systems and networks, and postgraduate students. |

Thus, an appropriate model for this function can be chosen, such as one valid for

a first-order PLL [5], that is, exp(2pD cos <p) w^= *Zw (4-78) where /0 is the

modified Bessel function of the first kind and the zero-th order. The
