In this article, we discuss radio‐over‐fiber (RoF) technologies that use TOSA and ROSA packaging to support the implementation of 700 MHz up to 6 GHz wireless systems integrated with optical fiber networks. The CWDM technology is employed for RoF transceiver which is used to provide high bandwidth and supply flexible multi‐input multi‐output (MIMO) antenna in broadband optical‐wireless access networks. In the transmitter end, distributed feed‐back laser diode is driven by RF amplifier and optical signal is coupled into PLC MUX via 4 lens. In the receiver end, the optical signal is DE‐MUX and coupled into 4 PDs. TIA amplifiers has a high linear gain is employed. The signal integrity is also calculated and analyzed in this paper. The NF, IIP3, and transmission performance is measured and about 2% the EVM is achieved under works for OFDM 64 QAM signal.

In this work optical solitons carrier generation in a nonlinear waveguide microring resonator (MRR) is simulated and presented. Therefore, a system comprises of a W-band (75 to 110 GHz) optical millimeter wave generation using a Panda microring resonator (PMRR) is presented. A bright soliton with a central frequency of 50 GHz and power of 1 W is introduced into the PMRR. The optical Kerr effect manifests itself temporally as self-phase modulation, a self-induced phase- and frequency-shift of a pulse of light as it travels through a medium. Large bandwidth within the microring device can be generated by using a soliton spectrum input into the nonlinear PMRR. The 90 GHz free spectral range (FSR) solitonic signals were simply generated by adjusting the system parameters. By beating the closely center frequencies of the solitonic signals, we can obtain a center frequency which corresponds to that spacing as millimeter wave used for many applications in signal processing and communications such as wireless cable systems and indoor–outdoor communication.

“…Nonlinear behaviors associated with light traveling inside a fiber optic ring resonator can be caused by the effects such as the Kerr effects, four-wave mixing, as well as the external nonlinear pumping electrical power [14,15]. This sort of nonlinear behaviors usually are called chaos, bistability, in addition to bifurcation.…”

Abstract:In this paper, we propose a system of microring resonator (MRR). This system uses a laser diode input which can be incorporated with an optical add/drop filter system. When light from the laser diode feedbacks to the fiber ring resonator, the pulses in the form of soliton can be generated by using appropriate fiber ring resonator parameters and also the input power. The filtering process occurs during the propagation of the pulse within the ring resonators. The full width at half maximum (FWHM) or bandwidth characterization of the pulse can be performed using the proposed system. Results obtained have established particular possibilities from the application such as optical network communication. The obtained results show the effects of coupling coefficients and ring radius on the bandwidth of the soliton pulse, where the graph of the FWHM versus the variable parameters such as the radius and coupling coefficient are presented.
