Abstract
A novel radio-over-fiber (RoF) system with V-band and W-band millimeter-wave (MMW) signals is proposed. We begin our simulation by first utilizing a 20 GHz local oscillator (LO) to drive a dual-parallel Mach-Zehnder modulator (DP-MZM) and generate two quadruple-frequency-interval coherent optical carriers. And then we use a dual-drive Mach-Zehnder modulator (DD-MZM) to load signal data and realize an optical single side-band (OSSB) modulation. Following these transmitted signals, we add a 50 km single-mode fiber (SMF) for signal transmission and a photonics detector (PD) for signal self-heterodyning detection. Thanking to the mitigated chromatic dispersion (CD) effect of OSSB signals, the eye opening in the eye diagram is observed even after the transmission over 50 km of the SFM spool. The power penalties of the generated V-band 60 GHz and the W-band 100 GHz MMWs at a 10−9 bit-error-rate (BER) are 1.7 dB and 2.5 dB, respectively.
