Abstract
In this paper, a 60-GHz photonic millimeter-wave link system for short-
to medium-range broadband wireless data transmission is investigated. The
system employs advanced mm-wave photonic components and radio-over-fiber (RoF)
techniques for the generation of a DSB-SC optical mm-wave carrier and its
subsequent on-off-keying modulation and transmission. For short-range applications,
we have constructed a compact wireless RoF transmitter consisting of a high-frequency
photodiode and a mm-wave antenna only. This system achieved error-free (BER = 10<sup>-9</sup>, 2<sup>31</sup> - 1 PRBS, NRZ) in-door transmission
of 12.5-Gb/s signals over wireless distances up to 3.1 m with a receiver sensitivity
as low as -45.4 dBm. For fixed wireless access (FWA) requiring
a bit error rate of $10<sup>-4</sup>,
the maximum transmission distance for 12.5 Gb/s is increased up to 5.8 m.
For medium-range broadband wireless transmission an electrical radio-frequency
(RF) amplifier was employed in the RoF transmitter. Here we achieved 7.5-Gb/s
error-free transmission in out-door line-of-sight experiments over wireless
distances of up to 36 m. Based upon the experimental results, we expect that
the maximum wireless distance the system could accommodate for 12.5 Gb/s is
in the kilometer range when using high-gain antennas and an RF transmitter
amplifier with a sufficient bandwidth.
