“…Based on this concept, several components have been developed, which achieve better performance than conventional ones by optimizing the circuit at the specified frequency bands. For example, an MMW optical modulator was proposed that employs an inverted slot line to achieve perfect velocity matching at the specified band and to achieve deep modulation [19], [20].…”

This paper describes work on wide-band millimeterwave (MMW)/optical-network applications in Japan-in particular, projects being pursued at the Advanced Telecommunications Research Institute (ATR). Digital-signal transmission at 118 Mb/s was tested. Results of the experiments demonstrate that highspeed digital-signal transmission, with a total carrier-to-noise ratio (C/N) degradation of less than 1.2 dB from a modem at a BER of 10 06 , is feasible. Similarly, analog FM-signal transmission with a weighted S/N of more than 45 dB is also feasible at a signal bandwidth of 18 MHz and FM carrier frequency of 43.75 GHz. Based on these results, a demonstration system was constructed, and the feasibility of the system was confirmed. Several key technologies for system construction such as an MMW optical modulator and an MMW high-speed p-i-n detector and some related technologies are also described. In addition, an advanced system considered suitable for future high-speed mobile communications is proposed. This system employs an optical signal-processing multibeam antenna, where the direction of each sharp beam can be adaptively controlled.Index Terms-Beamforming network, millimeter wave, millimeter wave/optical interaction, millimeter-wave subcarrier system, mobile communication system, optical signal-processing antennas.
