T. Ohno et al., Transmission of millimeter-wave signals in a fiber-radio system using a unitraveling-carrier waveguide photodiode, IEEE PHOTON, 12(10), 2000, pp. 1379-1381
We employ a unitraveling-carrier waveguide photodiode (UTC-WGPD) to constru
ct a fiber-radio remote base station without a millimeter-wave amplifier. B
ER characteristics of the fiber-radio system do not degrade when the UTC-WG
PD is used even at a high optical input level of 10 dBm, We achieved error-
free transmission of BPSK data over a 20-km standard fiber and a distance o
f 1 m without a millimeter-wave amplifier in the base station. It is proved
that the fiber-radio system using the UTC-WGPD is capable of wireless tran
smission over a distance of 60 m in free space.
