Hybrid fiber-wireless transmission of 2-Gbps signals in 60-GHz band over a composite channel (10-km SMF/1-km MMF/6.5-m wireless) is experimentally demonstrated for gigabit inbuilding wireless access using simple direct modulation, optical upconversion and envelope detection.OCIS codes: (060.2330) Fiber optics communications; (060.5625) Radio frequency photonics. IntroductionMillimeter-wave (MMW) wireless communication is receiving tremendous research interests to explore the potential of broadband wireless data transmission in future wireless personal area networks (WPAN) to support bandwidth-hungry services such as high-definition television (HDTV), 3D gaming and high-speed data access. Due to the high atmospheric loss of MMW signal, radio-over-fiber (RoF) technique is generally considered as an attractive solution to extend the reach of MMW wireless networks. Several MMW RoF systems have been proposed and demonstrated recently in the literature [1][2][3][4]. Additionally, in all MMW bands, 60-GHz band has been considered to be standardized for future WPAN networks by several working groups such as ECMA, . In order to commercialize 60-GHz RoF systems for next-generation high-speed wireless networks, it is highly desirable to develop a system with less complexity and low power consumption transceivers as a large number of remote antenna units (RAUs) and user terminals are to be deployed in the networks.Regarding the optical fiber plant, single-mode fibers (SMFs) have been widely deployed in optical core/metro/access networks, and well studied in the previously proposed MMW RoF systems. On the other hand, multi-mode fibers (MMFs) are predominantly deployed in in-building networks as a backbone for local area networks (LANs) (approximately from 85% to 90%) due to several advantages such as low cost, easy installation and maintenance [8]. When developing a system to meet the increasing demand for high-bandwidth services, it is greatly encouraged to efficiently utilize this existing infrastructure. Together with SMFs in access networks, the reuse of MMF for distribution of MMW signals through in-building optical networks to WPAN networks will tremendously save fiber reinstallation cost. The schematic of such system is presented in Fig. 1. MMW signal is generated optically at the central office (CO) and then distributed to user terminals through a composite channel including SMF, MMF and wireless link. Several experiments on MMF based RoF systems have been reported [9-11 and references therein]. However, to the best of our knowledge, 60-GHz over MMF system has not been demonstrated yet. The reported highest frequency and data rate so far are 38.8 GHz and 900 Mbps over 100-m MMF [10]. Data transmission over a composite channel has been demonstrated at low bitrate and low RF frequency: 120-Mbps data at 31.14 GHz over 20-km SMF plus 300-m MMF and 3-m wireless link [11]. For future deployment of 60-GHz system, it is important to evaluate the performance of 60-GHz signal over such composite channel.In this pape...

“…Figure illustrates the schematic diagram of the digital coherent RoF system. Although conceptually similar to the typical architecture reported in, the downlink only requires one laser source at wavelength λ 1 . The incoming signal is polarization splitted, and each polarization is frequency shifted by an electrical sinusoidal oscillator at the SSB circuit (upper and lower sidebands).…”

The author numerically investigates the performance of a 100 Gb/s dual‐polarization quadrature phase‐shift keying (DP‐QPSK) coherent radio‐over‐fiber (RoF) system through deploying various lengths of standard single‐mode fiber (SSMF). The utilization of a microwave photonic integrated circuit (MPIC) as the core building block of this optical coherent RoF link both in downlink and uplink, combined with digital signal processing (DSP) has led to a new RoF scheme which demonstrated the feasibility to operate at the low input RF power. The performance of the RoF system with respect to the optical received power induced by channel SNR is also investigated. It has been demonstrated that for a 200 km length of fiber, a laser with a linewidth of less than 1 MHz results in the EVM compliant to the IEEE standards. It has been also verified that the link offers higher linearity and better receiver sensitivity compared to the conventional intensity modulated and directly detected optical communication systems.

“…All-optical frequency shifting offered by stimulated Brillouin scattering is limited by the fixed Brillouin frequency of a fiber and a complicated pump wave locking Photonics 2021, 8, 561 2 of 13 procedure. For heterodyne light communication systems, the conventional choice is an OSSB modulator followed by filter structure to isolate the desired shifted band [16][17][18][19]. The frequency response of the filter and temperature control to maintain alignment among the source, modulator, and filter make the conversion procedure complicated and power hungry.…”

A photonic frequency shifter based on generalized Mach-Zehnder interferometer (GMZI) architecture is presented and experimentally validated. The circuit consists of four Mach-Zehnder modulators (MZM) in a 4 × 4 network bounded by two 4 × 4 multimode interference couplers and functionally equivalent to two parallel dual-parallel MZM (DP-MZM). The circuit can offer static bias free operation, virtual connectivity control of the components, and spatial separation of up- and down-converted carriers, which can be collected from separate ports without using any optical demultiplexing filters. Thus, the design permits remote heterodyning (advantages which cannot be obtained using a commercial DP-MZM or filter based optical frequency shifter). Experimental investigation shows deviation from ideal performance due to possible fabrication error and poor fiber-chip coupling. A carrier suppression of >20 dB and spurious sideband suppression >12 dB relative to the principal harmonics is achieved without any tuning for bias adjustment. In addition to the frequency conversion, the integration feasible circuit can also perform as a sub-carrier generator, IQ modulator, and frequency multiplier.
