Direct Detection in Optical Communication Using Intensity Modulation

ABSTRACT

Optical wireless communication (OWC) refers to communication through an unguided medium using modulated light. In this paper, the performance of OWC systems employing intensity modulation and direct detection (IM-DD), established by modulating Continue reading

Using Matlab Tools for Simulation of the Optical Transmission Medium

ABSTRACT

The paper presents a design and simulation of the optical path which include linear and nonlinear effects using the MATLAB simulation tools. The program includes a calculation part of nonlinear effects and a simulation part where the signal is examined Continue reading

Numerical Analysis of Orbital Angular Momentum based Next Generation Optical SDM Communications System

ABSTRACT

In this paper, we make a theoretical and numerical analysis of a transmission chain based on an Orbital Angular Momentum (OAM) technique in the case of ideal channel. In order to generate an OAM beam, we define a theoretical OAM encoder (vortex generator) similar Continue reading

The Laser Satellites Communications and Laser Noises

ABSTRACT

The gain of advanced optical communication systems is reduced by the noise of optical source. Coherent optical communication systems are in particular very sensitive to the noise transmitter and local laser. Optical space communications is on the verge Continue reading

Simulation and Animation in Optical Fiber Communication

ABSTRACT

Students find certain concepts in fiber optic communication theory difficult to grasp. A classic example is electromagnetic mode theory in cylindrical coordinates. The solutions of the differential equation which describe the modes of the fiber are Bessel Continue reading

MATLAB Simulink Simulation Platform for Photonic Transmission Systems

ABSTRACT

High speed and ultra-high capacity optical communications have emerged as the essential techniques for backbone global information transmission networks. As the bit rate of the transmission system gets higher and higher 40 Gb/s to 100 Gb/s the Continue reading
