Ultra-Short Solitonic Pulses Used in Optical Communication

Abstract

Microring resonators (MRRs) have shown great promise for application in many research areas such as optical communications in the micro- and nanoscale regime. An optical soliton is a powerful laser pulse that can be used to enlarge the optical bandwidth during propagation within a nonlinear MRR. The advantage of the proposed system is that the transmitter can be fabricated on-chip or operated alternatively by a single device. The MRR’s performance can be described in terms of several parameters such as the free spectrum range (FSR), full width at half maximum (FWHM), and finesse. MRR systems, provides the foundation for the development of new transmission techniques. Traveling of light inside the proposed ring system is analyzed by manipulating of nonlinear refractive index, coupling coefficient and the radius of the ring resonator. Therefore, controlling the round trip times and the input power of the system can be used to deal with and control the bifurcation and chaotic signals, where it is used in many applications in photonics communication such as signal processing or digital implementations. Ultra-short high quality soliton signals can be performed and transmit via a network system. Here, the optical information can be generated by large bandwidth of the arbitrary wavelength and frequency of light pulse signals via a series of MRRs device. Optical communication capacity can be increased by the multi soliton pulses generation. These type of signals are used widely to generate quantum data applicable to quantum network communication.
