Abstract :
A simultaneous modulation using a single 60 GHz-band EAM and fiber-optic transmission of 2.5 Gb/s baseband, microwave-band, and 59.6 GHz 155.52 Mb/s differential-phase-shift-keying (DPSK) signals on a single wavelength and transmission over 40 km-long dispersion-shifted fiber (DSF) are experimentally demonstrated. The optimum 3-band operation conditions are investigated. The degradation due to the non-linearity of the EAM for millimeter-wave signals is also investigated theoretically.
