“…In sections (A) and (B), it is shown that the impact of phase fluctuations on received signal can be vanished using an ED. By replacing σ with zero and considering QPSK modulation (PAPR = 1), (16) can be rewritten as…”

“…In [14], the impact of phase noise on different electrical down-conversion methods in RoF system based on PMLLD has been studied. The propagation effects in RoF system based on PMLLD are also presented in [15] and [16]. However, a complete study of amplitude noise impact, including the optical source noise, on Signal to Noise Ratio (SNR) and EVM, and also their comparison in RoF systems based on PMLLD and two DFB lasers have not yet been done, to our knowledge.…”

In this paper, a complete theoretical and experimental study of amplitude noise impact on performance of radio-overfiber (RoF) communication system in millimeter-wave (MMW) frequency band is presented. A simulation method is also presented, using which one can determine the origin of the amplitude noise which has the most impact on error vector magnitude (EVM). This method is based on analyzing the trends of EVM versus received optical power. The impact of different optical and electrical noise such as relative intensity noise, shot noise and thermal noise on EVM is precisely studied employing experimental and theoretical analysis. In the proposed RoF system, two techniques are used to generate MMW signal, and the EVM results are compared from amplitude noise viewpoint. In the first technique, two independent distributed feedback lasers are used to generate MMW signal at the output of a photodetector, and the second technique is based on a passively mode-locked laser diode. Impact of optical sources phase noise on performance of the system is removed using a noncoherent down-conversion method based on envelope detector. Using this method, a very good matching between the experimental and the simulation results is observed.Index Terms-Distributed feedback (DFB) laser, envelope detector, error vector magnitude (EVM), millimeter wave (MMW), passively mode-locked laser diode (PMLLD), phase noise, radioover-fiber (RoF), relative intensity noise (RIN), shot noise.

“…3, it can be seen that the MMW power reaches a second maximum at 2140 m after traveling a further distance of 2070 m along the SMF for which the modes become again in phase [6]. This periodicity length is directly linked to the 58.37 GHz spacing between laser modes and to the chromatic dispersion of the SMF [3]. Both periodicity length and generated MMW frequency have been experimentally verified.…”

In this paper, a method is proposed to reduce the sensitivity to chromatic dispersion over a fiber optic link based on mode-locked lasers for Millimeter Waves (MMW) generation and transmission. The simulation presented here gives an estimation of the length margin of fiber available for radio-over-fiber networks with minimal sensitivity and maximum received MMW power. The simulation results are verified experimentally by means of a 60 GHz mode-locked laser system combined with an unbalanced Mach Zehnder interferometer for the compensation of the impact of dispersion effects on transmitted MMW power and fiber length range.Index Terms-Chromatic dispersion, fiber link, millimeter waves (MMW) generation and transmission, mode-locked laser diode (MLLD), radio over fiber (RoF), unbalanced Mach Zehnder interferometer (UMZI).

“…As a modulated laser beam, we employ an InAs/InPbased quantum dash mode-locked laser diode self-oscillating at 58.625 GHz with around 5 mW output power [30]. In order to compensate for the laser dispersion, we use 70 m of a SMF-28 single mode fibre while a variable optical attenuator allows us to vary the average optical power that excites the PSW.…”

Characterization of nitrogen ion implanted InGaAs photoconductive devices is performed in both the electronic and optoelectronic regime. In the dark state, the optoelectronic device shows a dark resistance of a few kΩ and a wide electrical bandwidth in the RF domain. This large bandwidth is also confirmed in the illuminated state, optoelectronic autocorrelation experiments performed with ultra-short optical pulses allow us to measure the picosecond optoelectronic time response of the device. In the second part of the work, we investigate the potentiality of this component to be used in the photonic assisted heterodyne detection of RF modulated carriers for radio-over-fibre telecommunications. We demonstrate that this photoconductor, thanks to its properties, can be used to demodulate complex data modulation formats in such an experiment.
