“…Radio-on-dense-wavelength-division-multiplexing (DWDM) transport systems, which combine the advantages of fiber optics and wireless radio communications, have been developed with high expectations for future communications that require broad bandwidth and high speed access [1][2][3][4][5]. As radio-on-DWDM penetrates into the optical network, more benefits like capacity upgrade and network flexibility can be achieved.…”

A bidirectional radio-on-dense-wavelength-division-multiplexing (DWDM) transport system for local area network (LAN) (11 Mbps/2.4 GHz) and intelligence transport system (ITS) (20 Mbps/ 5.8 GHz) applications based on direct-detection scheme is proposed and demonstrated. By this way, the RF power degradation introduced by fiber dispersion can be avoided since optical carrier and one of the sidebands are eliminated before detecting. Over a-50 km single-mode fiber (SMF) transmission, good bit error rate (BER) performances (10 −9 ) were achieved in our proposed systems. Such proposed bidirectional radio-on-DWDM transport systems are suitable for microwave optical links.

“…Given its important, multi-lateral role the AND gate has attracted intense research interest and among the technological options that exist for its implementation those that exploit a semiconductor optical amplifier (SOA) are well established [17]. In fact, besides being employed for classical applications such as signal generation [18], amplification [19] and modulation [20], SOAs have also demonstrated their potential as nonlinear switching elements for performing all-optical AND logic, either as stand-alone entities [21][22][23][24][25][26][27] or incorporated in an interferometric configuration [28][29][30][31][32].…”

Abstract-The feasibility of realizing an all-optical AND gate for 320 Gb/s return-to-zero data by incorporating quantum-dot semiconductor optical amplifiers (QD-SOAs) in a Mach-Zehnder interferometer (MZI) is theoretically investigated and demonstrated. The proposed scheme employs the QD-SOA-based MZI in a configuration where the QD-SOA in one MZI arm is subject to the first data sequence, the QD-SOA in the other MZI arm receives no such input but is constantly held in the small signal gain regime, and the second data stream is inserted from the common MZI port acting as enabling or disabling signal. Compared to other approaches adopted for the same purpose this implementation is more general, direct, flexible and affordable as only one strong data signal is required to control switching. By conducting numerical simulation the impact of the critical parameters on the Q-factor is thoroughly assessed. The obtained results are interpreted with the help of a complete characterization of the QD-SOA response to an ultrafast data pulse stream. This allows to specify the requirements that the critical parameters must satisfy to achieve acceptable performance. The extracted design rules are technologically realistic and ensure AND operation both with logical correctness and high quality. The outcome of the numerical treatment extends the range of Boolean functions executed with the QD-SOA-MZI module at sub-Tb/s data rates.

“…Among the applications is the radio-over-fiber (RoF) system in which radio or wireless signals on a microwave subcarrier are transmitted through an optical carrier over optical fibers. Sharing the intrinsic merits of optical fibers, RoF systems have the advantages such as reduced size, weight, and cost, low attenuation, immunity to electromagnetic interference, low dispersion, and high data transfer capacity [6,7]. The original data to be transmitted from the central office is generally at the baseband or an intermediate frequency.…”

Nonlinear dynamics of an optically injected semiconductor laser for microwave frequency mixing are experimentally investigated. Through optical injection, the laser is driven into the nonlinear periodone (P1) dynamical state and acts as a broadly tunable photonic microwave oscillator. With an external current modulation at an intermediate frequency, the P1 oscillation is modulated accordingly, thus achieving frequency up-conversion beyond the laser bandwidth. Using a 2.5-Gbps-grade laser, binary phase-shift keying (BPSK) data signal is up-converted from an intermediate frequency of 2 GHz to a subcarrier frequency as high as 20 GHz. While the direct modulation bandwidth limits the intermediate frequency, it does not limit the subcarrier frequency. The approach uses only low-cost lasers and requires no high-speed electronic mixers.
