Design and Investigation of Modal Excitation in Tapered Optical Fiber for a Mode Division Multiplexed Transmission System

Abstract

One of the main advantages of optical communication is its potential to transmit messages through the same channel via multiplexing. The concept of Mode Division Multiplexing (MDM) technology was first suggested to the telecommunication industries as a substantial solution to decrease the cost per bit of optical fiber transmission. This article aims to transmit information with less possible noise. To achieve this, multiple transverse modes are used to deliver information from the transmitter to the receiver. Our design evaluated a tapered nature that excites a total of 20 modes. In the evaluation, we applied Fourier transformation to the modes. We combined two, three and four modes to test the different complex mode mechanisms they produce in amplitude and phase.
