We demonstrate 300-GHz-band radio transmission with a digital coherent detection technique. Quadrature-phase-shift-keying modulation can provide a data rate of 29.9 Gb/s, with 7% forward error correction overhead. A frequency-locked optical frequency comb for a 300-GHz radio-over-fiber signal can be generated by a recirculating frequency shifter with a singlesideband suppressed-carrier modulator in...
In this work we demonstrate a novel long reach wavelength division multiplexing passive optical network (WDM-PON) backhauling scheme for future optical-wireless access systems. The topology is based on amplified spontaneous emission (ASE) injected into reflective semiconductor optical amplifiers (R-SOAs) to implement colorless ONTs and hybrid EDFA-Raman amplification, to allow long-reach. We investigated...
