“…A periodic grating structure will be formed by the acoustic wave. The SBS effect refers to two beams of optical signals which are transmitted in opposite directions [22]. Once the power of the pump light exceeds the threshold condition of the pump light, the SBS effect will occur when the propagating Stokes wave with frequency of − as the optical carrier can be generated from port-3 of the OC in the opposite direction, as illustrate in Fig.…”

We present a novel and simple scheme for all-optical microwave photonic frequency converter, free of electrical components, based on stimulated Brillouin scattering (SBS) effect. An SBS-based frequency shifter is incorporated to generate Stokes wave whose frequency is down-shifted by , where is defined as the Brillouin frequency shift. With a tunable optical passband filter, the up/down frequency conversion can be realized through the same structure. In the proof-of-concept experiment, the microwave signal at 1 to 15 GHz can be up-converted while the microwave signal at 11 to 29 GHz can be down-converted by the microwave photonics frequency converter. Moreover, the frequency and power stability of the generated signals are also investigated in three hours. To vindicate flexibility, low cost and easy implementation of the proposed all-optical setup, an experiment is carried out, and it turns out that only the frequencyto-be-converted signal source is needed while providing the ultra-wideband up/down conversion.

“…6. At first, a pseudorandom bit sequence (PRBS) data with a pattern length of 2 15 −1 was mapped onto M-QAM symbols and was arranged in the time-frequency transformation matrix with the FFT size. Note that the M-QAM symbols in the time-frequency transformation matrix are arranged with Hermitian symmetry to obtain a real-valued DMT time-domain waveform after IFFT.…”

By using a multi-color laser diode carrier with orthogonal polarization and single-carrier modulation, the long-reach single-mode fiber (SMF) passive optical network and millimeter-wave wireless access network (WAN) with carrying narrow-band and channelized discrete multitone (DMT) data format at >1 Gbit/s/channel are demonstrated for 5G wireless mobile applications. For fiber wireline transmission from central office to remote node, the multi-color laser diode is directly encoded by DMT with quadrature amplitude modulation (QAM) levels ranged from 64 to 1024, and the total raw data rate of the received DMT can maintain as high as 88 Gbit/s at a limit modulation bandwidth of 9.125 GHz. The allowable data band consisting of 0.07-6 GHz for 1024 QAM, 6-9 GHz for 512 QAM and 9-9.125 GHz for 256 QAM is achieved even after long-reach transmission in 75-km-long SMF spool. For wireless transmission from remote node to user end with 28-GHz millimeter-wave carrier after optical heterodyne, the wireless transmission distance can lengthen up to 10 meters with allowable data capacity optimized to 29.6 Gbit/s with a modulation bandwidth of 4.1 GHz in total. Consequently, the achievable bit-loaded data band is 256 QAM within 0.07-2.5 GHz and 64 QAM within 2.5-4.1 GHz for 5G mobile WAN transmission via horn antenna pair.
