“…It will greatly affect the transmission performance of the ROF system. The conventional data modulation formats for the optical MMW in ROF are single sideband (SSB) modulation, double sideband (DSB) modulation, and optical carrier suppression (OCS) [ [26] , [27] , [28] , [29] ]. In the optical MMW, (a) when there are two sidebands with the optical carrier, it is regarded as the generalization DSB; (b)when there are two sidebands without an optical carrier, it is regarded as the generalization OCS; (c)when there is one sideband with the optical carrier, it is regarded as the generalization SSB.…”

“…To overcome this problem, a number of techniques involving the simultaneous transmission of the LO and data signals from the CO to the BSs have been proposed. These techniques include the transmission of the LO at a mm-wave frequency [3], or as a lower frequency harmonic of the LO [4], [5]. However, such schemes have drawbacks for application in a multisector fiber radio network, such as spectral inefficiency, the potential to generate higher order side modes or the requirement for complex electronics in the BS [3]- [5].…”

We propose and demonstrate a fiber Bragg grating (FBG)-based optical interface for use in a spectrally efficient fiber-radio network with multisector antennas. The system has the novel feature of being specifically developed for use in existing wavelength-division-multiplexed network infrastructures. The proposed scheme supports transport of a remote local oscillator (LO) and three subcarrier multiplexed data channels, destined for different antenna sectors, using a single wavelength. The composite signal was contained within a 25-GHz band, selected via a 25-GHz dispersion-flattened FBG. Recovery of the LO and data channels is performed via optical filtering, using either a novel single grating incorporating multiple phase shifts or multiple narrow bandwidth gratings. Our measurements show that all channels within the 25-GHz band are successfully recovered with less than 2-dB optical power penalty between channels. The use of the 25-GHz grating exhibits an improvement in sensitivity of 3 dB for all data channels.

We have investigated the generation and transmission of optical millimeter (mm)‐wave signal based on optical phase modulator (PM) and fiber Bragg grating (FBG) filter. With an optimized modulation depth of PM and a higher carrier suppression ratio via a notch filter, the generated optical mm‐wave can be transmitted over a long‐distance without fading. We have also theoretically analyzed the impact of time shift on the eye closure of optical and electrical signal due to the fiber dispersion, which is well in accord with the experimental results. © 2007 Wiley Periodicals, Inc.
