For the purpose of revisiting the semiconductor optical amplifier (SOA) ability for large-band
amplification in the context of wavelength division multiplexed (WDM) coherent systems, we …

The linearization performance of various digital baseband pre-distortion schemes is
evaluated in this paper for a coherent optical OFDM (CO-OFDM) transmitter employing a …

In this paper, we investigate the usage of SOA for reach extension of an impulse radio over
fiber system. Operating in the saturated regime translates into strong nonlinearities and …

In this paper, three orthogonal frequency division multiplexing (OFDM) bands of 400 MHz
are successfully transmitted over 20 km of single-mode fiber (SMF). The framework is that of …

In order to mitigate second-order intermodulation distortion products, induced by the
interaction between the Mach-Zehnder modulator, the photodiode and the semiconductor …

Digital predistortion is topic of significant interest in telecommunications–both in the wireless
radio field and, more recently, in photonics. In the present letter, the authors undertake a …

The joint use of peak-to-average power ratio (PAPR) reduction and linearization via digital
predistortion is investigated in this letter, with the view to improve the performances of …
