Coupled hybrid active doped fiber and Fabry-Perot diode laser

The Fabry-Perot laser diode coupled with external erbium doped fiber (EDF) terminated with a reflector forms the hybrid diode/EDF laser. The Fabry-Perot laser plays a role of spectral etalon with internal controlled gain for the linear erbium doped fiber laser when the main spectrum of longitudinal modes of Fabry-Perot laser overlaps the main gainband of erbium doped fiber amplifier. This idea has been proved experimentally. The hybrid diode/EDF laser can oscillate in multimode regime and it can simulate multichannel coherent source for Wavelength Division Multiplexing when only free spectral range of the Fabry- Perot diode lasers overlaps with ITU channel spacing.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.
