Optical Communication with Weak Coherent Light Fields

Development of Semiconductor Laser for Optical Communication

The performance, functionality and productivity of the semiconductor laser have been dramatically improved since its invention in 1962. Today it came to be indispensable for our life as optical components connecting home and the Internet as well as long-distance large-capacity trunk networks. It may be said that the information revolution pulled by the explosive spread of the Internet is origin...

Study on Characteristics of Distributed Feedback (DFB) LASER as Light Source for Optical Fiber Communication System

This paper represents the study of light sources for optical communication through the optical fiber. For this purpose, the ideal light source characteristics have been studied. According to the study, the semiconductor LASER diodes are preferable sources over LEDs. From the family of LASER diodes, Distributed Feedback (DFB) lasers are considered as source. They have low threshold current and h...

Coherence and visibility for vectorial light.

Two-path interference of transversal vectorial waves is embedded within a larger scheme: this is four-path interference between four scalar waves. This comprises previous approaches to coherence between vectorial waves and restores the equivalence between correlation-based coherence and visibility.
