The polarization sensitivity of semiconductor optical amplifiers can be assessed in terms of gain or in terms of induced phase shift. Although the former aspect has received a lot of attention, the… (More)
We present a new WDM-PON architecture based on amplified self-seeded RSOA creating an external cavity source. The SMF cavity length can reach up to 45km. Transmission at 2.5Gb/s are demonstrated.
This paper presents the first demonstration of the use of a periodically poled lithium niobate device for signal processing at 640 Gbit/s. Clock recovery is performed successfully using the lithium… (More)
Optical injection locking and optical phase-lock loops have been used for laser synchronization. The use of a combined optical injection locking and phase-lock loop system is proposed here. We have… (More)
A self seeded WDM PON solution is evaluated at 1.25Gb/s and 2.5Gb/s in order to address optical budget, rise and fall time and jitter performances issues.
Clock recovery is a critical function of any digital communications system. To replace the classical electronic phase-locked loops (PLLs) at higher bit rates, several all-optical or optoelectronic… (More)
An external cavity laser is demonstrated with a RSOA at ONU and a mirror at the RN which can be 5km away. A record transmission of 10Gbits/s is shown and compared with performance at 1.25, 2.5,… (More)
A 3 times 8 all-optical decoder based on cross-polarization modulation in semiconductor optical amplifiers is demonstrated for the first time to our knowledge. The design requires a single active… (More)
We report on a simple and fast method to estimate the fiber dispersion and laser chirp parameters on a dispersive Intensity Modulation and Direct Detection (IM/DD) optical channel. Based on the… (More)
The objective of this research is to propose two new optical procedures for packet routing and forwarding in the framework of transparent optical networks. The single-wavelength label-recognition and… (More)
