“…A 35 km repeater spacing was achieved, and it was proposed that such a system would be useful as a satellite-station entrance link. In a similar experiment, a C-band satellite signal carrying fm video, 3 Mb s-1 qpsk and 60 Mb s-1 qpsk signals was transmitted over 20 km (Bowers et al 1987). In this paper it is shown that scm techniques can be extended to transmission of very large numbers of information channels for a broadband subscriber network (Olshansky 1987).…”

The use of microwave carrier frequencies in wideband optical-fibre networks is a promising new approach to the distribution of voice, data and video services to subscribers. This paper discusses the general features and design rules of microwave multiplexed wideband optical-fibre systems and reports on several specific systems developed at GTE Laboratories. These include transmission of 60 frequency modulated (FM) video channels multiplexed on carriers in the 2.7-5.2 GHz band, and the transmission of 20 frequency-shift-keyed (FSK) 100 Mb s -1 digital video channels in the 2-6 GHz band. A hybrid system is also described that transmits a 100 Mb s -1 baseband signal in addition to the 60 FM video channels. These transmission experiments illustrate the large bandwidth capability and design flexibility of microwave-multiplexed lightwave systems. As lightwave systems push towards larger and larger bandwidths, microwave-multiplexing may emerge as the more natural way to exploit the enormous bandwidth of lightwave components.

“…1. The receiver is built around a standard optical mixing based phase detector with a differential output signal current given by (1) Where and are signal and LO optical power, and are optical phase and is the responsitivity of the detector. This signal is then amplified to form a driving voltage to a tracking optical phase modulator (2) where are detector and modulator impedances and is the amplifier transimpedance.…”

“…Since the transport is performed in the optical domain, the link itself is immune to electromagnetic interference. Original work on radio over fiber was considered for satellite communication applications [1]. More recent efforts have primarily focused on wireless mobile communication systems [2], where the relatively linear response of inexpensive directly modulated sources [3], [4] make moderate performance inexpensive links attractive for this application.…”

Abstract-In this paper, we present a coherent receiver based on an optical phase-locked loop (PLL) for linear phase demodulation. The receiver concept is demonstrated at low frequency. For high-frequency operation, monolithic and hybrid integrated versions of the receiver have been developed and experimentally verified in an analog link. The receiver has a bandwidth of 1.45 GHz. At 300 MHz, a spurious free dynamic range (SFDR) of 125 dB Hz 2 3 is measured.

“…Recently, photonic generation of RF, microwave and millimeterwave signals has been widely studied. This technique uses the optical fiber as the transmission medium for considerably stable carriers that are generated in a wide range of RF and microwave frequencies, with applications on mobile communication [1][2], satellite communications [3], and subcarrier multiplexed systems [4]. Techniques such as optical phase-lock loop [5] [6], injection locking [7] and mode-locking [8] have demonstrated the feasibility of the optoelectronic conversion and generation of RF and microwave carriers.…”

The gain-crossed property of semiconductor optical amplifiers is experimentally investigated. It was observed that optically feedbacked saturated amplifiers could achieve similar performance as that of cascaded amplifiers, offering up to 10 dB gain to two 8-nm-appart modulated optical carriers. Due to saturation, the amplifier gain mechanism is altered, leading to a mixing effect that causes the frequency components of the optical signals to be exchanged. For optical carriers modulated at 250 MHz and 400 MHz, this mixing effect produced, after photodetection, up and down-converted electronic components at 150 and 650 MHz, respectively.
