Error-free transmission over 20km of 8-channels for both downstream and upstream in colourless WDM-PON based on injection-locked Fabry-Perot laser is experimentally demonstrated at 2.5Gbit/s, using a single quantum dash mode-locked laser as multi-wavelength seeding source. Introduction To meet the bandwidth demand of next generation optical access network… (More)
Error-free colorless WDM-PON downstream over 25 km for 16 channels with 85 GHz channel spacing is experimentally demonstrated at 2.5 Gbit/s, using an injection-locked Fabry-Perot laser and a quantum dash mode-locked laser as a coherent seeding source.
Injection-locking is based on the fact that the laser can be locked onto the frequency and the phase of an external injected optical signal. When a Fabry-Perot laser diode (FP LD) is locked onto a single-mode signal, its operation becomes single-mode. The injection-locked FP LD (IL-FP LD) has been proposed as a standard component for optical access network… (More)
In this paper we present our recent works on optical injection of Fabry-Perot laser diode for application in access networks. The injection-locked Fabry-Perot laser diode is used as low-cost colorless transmitters for high-speed optical access exploiting wavelength-division-multiplexing technology. The modification of main characteristics of Fabry-Perot… (More)
RESUME Une architecture de réseau d'accès optique multiplexé en longueur d'onde (WDM-PON) utilisant des émetteurs achromatiques à base de lasers Fabry-Perot verrouillés en longueur d'onde par injection optique est proposée. Une source multi-longueur d'onde composée d'un seul laser à modes bloqués à bâtonnets quantiques est utilisée pour verrouiller les… (More)
As a result of the low modulation efficiency of carrier-depletion Mach-Zehnder silicon optical modulator, it always needs a high voltage around 6 V, which is very difficult to supply in an integrated high-speed CMOS chip. We demonstrate a carrier-depletion Mach-Zehnder silicon optical modulator which works at a low voltage. Its coplanar waveguide electrode… (More)
This paper presents our work carried out in the colorless-component technologies for high bit-rate optical access networks, which are based on WDM-PON (wavelength division multiplexed passive optical networks). The colorless concept consists in using identical and wavelength-independent components that will act as the generic transmitter in WDM-PON systems.… (More)
