High‐capacity soliton transmission for indoor and outdoor communications using integrated ring resonators

Abstract

SUMMARYA system consisting of a series of microring resonators, incorporating an add/drop system, is presented in order to create ultra‐short spatial and temporal single and multisoliton pulses, which can be used for indoor and outdoor optical communications. Chaotic noise can be generated by a bright soliton pulse propagating inside a nonlinear microring resonator system. The results obtained show that a single temporal and spatial soliton pulse, with full width at half maximums of 75 fs, 80 fs, 700 fs, 4.4 ps, and 0.30 nm, can be generated. The add/drop system can be used to generate a high number of ultra‐short soliton pulses in the ranges of nanometer/second and picometer/second. The simulated multisolitons have full width at half maximums of 16 ps, 20 pm, 130 ps, and 35 pm and free spectrum ranges of 500 ps, 0.57 nm, 3.5 ns, and 1.4 nm, respectively. The multisolitons generated at the drop port can be used in indoor optical communications, where the ultra‐short pulses with a variety of central wavelengths (from λ = 1550 to λ = 1560) from the through port can be multiplexed‐demultiplexed along an optical fiber with a length of 50 km. The filtered signals can be obtained at the end of the transmission link used for optical outdoor communications. Copyright © 2013 John Wiley & Sons, Ltd.

Optical Soliton Signals Propagation in Fiber Waveguides

“…Chaotic signals have some properties such as broadband, orthogonality and complexity aspects, which prompt researches in the areas of nonlinear science, communication technology and signal processing [64][65][66][67]. The concern in chaotic communications was due to the foreseen good properties of the chaotic signals in the fields of security systems or broadband multiple access systems.…”

“…[20][21][22] The long distance communication can be performed by using high optical output of the soliton signals within the ring resonator system. [23][24][25] A soliton band can be generated by using a Gaussian pulse propagating within a ring resonator system. [26][27][28] We use a system of MRRs connecting to a panda ring resonator to generate a high frequency band of optical soliton pulses.…”

Full Width at Half Maximum (FWHM) Analysis of Solitonic Pulse Applicable in Optical Network Communication

“…One new feature of this specific type of ring resonator, which introduces a system of nanoscale-sensing transducers based on the add/drop ring resonator was presented by Amiri et al [10,11]. They have shown that the multisoliton can be generated and controlled within a modified add/drop ring resonator [12,13].…”
