- Abstract :
This paper proposes a fiber-optic millimeter-wave (mm-wave) uplink
system incorporating a 60-GHz-band photonic downconversion technique.
With this concent, neither a light source nor a mm-wave source is
required at a base station (BS) since the mm-wave modulated optical
pilot tone is fed from a remote central station (CS). In the BS,
a high-speed mm-wave electroabsoption modulator and a subsequent
optical bandpass filter are used for the photonic downconversion of
the received mm-wave signal, converting the 59.6-GHz mm-wave signal
into a 2.6-GHz intermediate frequency (IF) signal. The converted signal
is then transmitted through the uplink fiber system to the CS with
no significant chromatic dispersion effect. We successfully
demonstrated not only photonic downconversion,
but also 50-km-long fiber-optic transmission of the
downconverted 2.6-GHz IF signal with 156 Mb/s of data.
