Summary form only given. In recent years a dramatic expansion of internet data traffic has been reported[1]. To provide high data rates in two directions via optical fibers, several methods have been developed. Most of them require both at each end a light source to generate the data and a detector to receive the data[2]. Coupled semiconductor lasers - a system of two spatially separated nonlinear...Show More
