“…ponents E x and E y are as follows: [4] Fig.2, Fig.3 and Fig.4 show that this proposed scheme can be used to generate 0-120 GHz microwave or millimeter-wave signal. For example, a 1550 nm initial non-chirped Gaussian optical pulse with the pulse duration T 0 = 1 ps is first fully polarization scrambled, then it is put into the polarization maintaining fiber with the fiber length L= 10 km, and we assume that the dispersion coefficient of the fiber 2 is -20 ps 2 km -1 , and the group velocity delay D is 15 ps, consequently, the signal with frequency of 23.87 GHz can be achieved.…”

A new method is proposed to generate microwave and millimeter-wave by using polarization scrambler and polarization maintaining fiber (PMF), which is based on the coupling and the interaction between the two polarizations of the initial non-chirp Gaussian optical pulse in PMF. The expressions of the microwave and millimeter-wave are derived by couplemode theory. Moreover, the feasibility is analyzed simulatedly. At last, 0-120 GHz microwave and millimeter-wave can be produced by adjusting system parameter or input pulse duration. The project is of great simplicity, stability and high export efficiency.In order to provide high capacity and high quality information service, microwave communication and optical fiber communication have been developed. Meanwhile, microwave photonics (MWP) technology, which that of combines the advantages of microwave technology with optic technology, has been developed into a new area. It has the characteristics of low loss, electromagnetic interference resisting, broad band, high capacity and low cost. Radio over fiber (RoF) system in which microwave can be used as the subcarrier inside the fiber has various advantages when it is applied to analogue television system and wireless system, especially for mobile communication radio networks and intelligent traffic system (ITS) [1] .To generate microwave and millimeter-wave, it is very important to design simple and feasible RoF project. In recent years, lots of new methods to form microwave or millimeter-wave pulse, such as Moiré fiber Bragg grating method [2] , interleaver and plunged-single external optical modulator [3] , have been adopted.In this paper, a new method is proposed based on polarization scrambler and polarization maintaining fiber (PMF) to generate microwave and millimeter-wave signal. Fig.1 shows a schematic description of this system. The laser pulse transfers into a polarization scrambler, which makes the laser pulse fully polarization scrambled in order to get the same electric field strength between E 0x of x-axis polarization component and E 0y of y-axis polarization component. And then the pulse can propagate in the polarization maintaining fiber. The traveling pulse is separated into two polarization components, electric field E x and electric field E y , each aligns along the principal axis, x-axis and y-axis. Each component changes while propagating inside the polarization maintaining fiber because of group velocity delay and group velocity dispersion. As a result, the polarization state of the original input pulse is changed at the output of the fiber, we can suppose that the amplitude of the output linear polarization light wave is X out , and it is aligned at an angle with respect to the x-axis. At last we assume that the output intensity of the polarization detector is I out .

Graphene has excellent thirdorder nonlinear optical (NLO) properties due to its unique electronic band structure and wideband gap tunability. This paper focuses on the research progress of graphene and its composite materials in nonlinear optics in recent years. In this review, recent results on graphene (or graphene oxide)–metal nanoparticles (G-MNPs), graphene–metal–oxide nanoparticles (G-MONPs), graphene–metal sulfide nanoparticles (G-MSNPs), and graphene–organic molecular composites (G-OM) have been discussed. In addition, the enhancement mechanism of nonlinear absorption (NLA) and optical limiting (OL) have also been covered.

“…Bordonalli et al [7] improved the above scheme and reported a MMW signal generation by combining optical sideband injection locking with optical phase-lock loop techniques for two fiber-coupled DFB lasers. Apart from the above continuous-wave microwave and MMW signal generation devices, Levinson et al [8] put forward a method of synthesizing complex frequency modulation form microwave and MMW pulses by using dispersion and Kerr effect in optical fiber systems, and demonstrated the generation of electrical pulses modulated at a controllable microwave frequency using a Mach-Zehnder interferometer and a chirped fiber grating. Very recently, they also demonstrated [9] a broad MMW modulated pulses generation with a linear frequency chirp by using two fiber Bragg gratings and a mode-locked fiber laser.…”

A novel scheme is proposed to transform an optical pulse to a millimeter-wave frequency modulation pulse by using a fiber Bragg grating in radio-over-fiber system. The Fourier transformation method is used to obtain the required spectrum response function of FBG. Based on this target spectrum response function, the cases for a weak fiber grating and strong fiber grating are analyzed and the corresponding refractive index distributions are obtained. The performances of the fiber gratings are also studied by a numerical simulation method for an ultra-short pulse transmission.
