D. Wake et al., TRANSMISSION OF 60-GHZ SIGNALS OVER 100 KM OF OPTICAL-FIBER USING A DUAL-MODE SEMICONDUCTOR-LASER SOURCE, IEEE photonics technology letters, 8(4), 1996, pp. 578-580
High-purity 60-GHz signals, generated using a dual-mode DFB semiconduc
tor laser, have been transmitted over 100 km of standard optical fiber
with no observable degradation in purity. This device is shown to be
a simple and compact optical source of high-purity 60-GHz signals for
long-reach fiber-fed millimeter-wave radio systems.
