Two high-speed, high-capacity (20 Gbps–40 GHz) data-carrying signals are transmitted simultaneously over free space over the characteristic HG modes, HG00 and HG01. Through the use of a continuous wave (CW) laser and a multimode generator, the unique spatial optical modes are created (MMG). Using a 4-QAM generator, a 20 Gbps data-carrying laser beam is created for each channel. An optical OFDM modulator is now used to modulate the signal, using 1024 inverse fast fourier transform (IFFT) points spread across 512 sub-carriers. A quadrature modulator (QM) is used for further modulation. The modulated signal and a 40 GHz RF pulse are combined after passing through the mixer. In a Mach-Zehnder modulator (MZM), the signal is optically modulated after which it is broadcast ac...
