Self - Seeded RSOA - Fiber Cavity Lasers vs . ASE Spectrum - Sliced or Externally Seeded Transmitters — A Comparative Study

Reflective semiconductor optical amplifier fiber cavity lasers (RSOA-FCLs) are appealing, colorless, self-seeded, self-tuning and cost-efficient upstream transmitters. They are of interest for wavelength division multiplexed passive optical networks (WDM-PONs) based links. In this paper, we compare RSOA-FCLs with alternative colorless sources, namely the amplified spontaneous emission (ASE) spe...

Use of Fabry-Pérot lasers for simultaneous distributed strain and temperature sensing based on hybrid Raman and Brillouin scattering

In this paper we propose the use of multi-longitudinal mode lasers, such as Fabry-Pérot (FP) lasers, for simultaneous distributed strain and temperature sensing based on hybrid Brillouin and Raman scattering. Fabry-Pérot lasers allow for high-power Raman intensity measurement and the simultaneous detection of the Brillouin frequency shift parameter for all FP longitudinal modes, by using a self...

Using optical injection of Fabry-Perot lasers for high-speed access in optical telecommunications

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 laser such as spectral properties, noise ...

Enhanced Modulation Bandwidth of a Fabry–Pérot Semiconductor Laser Subject to Light Injection From Another Fabry–Pérot Laser

Variations in optical spectrum and modulation bandwidth of a modulated Fabry–Pérot (FP) semiconductor laser subject to the external light injection from another FP Laser is investigated in this paper. Optimal wavelength matching conditions for two FP lasers are discussed. A series of experiments show that two FP lasers should have a central wavelength overlapping and a mode spacing difference o...
