International Journal of Optics, Volume 2017, Issue 1, 2017., 2017 This paper demonstrates a 10 Gb/s one‐to‐two‐wavelength conversion configuration based on cross‐gain modulation for optical access networks using a single TW‐SOA. The method is capable of converting a signal data of specific wavelength 1541 nm to certain wavelengths of CW’s laser 1554 nm and 1558 nm with 4 nm spacing.

Amplified spontaneous emission pulses for high‐power supercontinuum generation
The Journal of Engineering, Volume 2016, Issue 3, Page 29-31, March 2016., 2016 The authors demonstrate an incoherent light source based on a reflective semiconductor optical amplifier as pump for high‐power supercontinuum generation for the first time. The obtained power level is about 160 mW and 20 dB spectral bandwidth is around 170 nm.

LTE transmission exploiting pulse width modulation in fibre optic links [PDF]
, 2017 Recently it has been demonstrated that pulse width modulation (PWM) can represent a viable solution for the analog optical fronthaul alternative to standard radio over fibre, which still avoids the bandwidth expansion of the digital fronthaul.
