Multiwavelength fiber laser sources with Bragg-grating sensor multiplexing capability

A tunable dual-wavelength erbium-doped fiber ring laser using a self-seeded Fabry-Perot laser diode

“…7, when the wavelength-tuning range was smaller than 9.46 nm the laser maintained the SMSR up to 31 dB. In contrast with the technique by inserting filters into the EDF laser cavity for multiwavelength oscillations [4]- [6], the dual-wavelength output can easily be tuned. The SMSR performance from our self-seeded scheme is also better than those from [7] and [8].…”

“…The wavelength competition originates from the homogeneous gain broadening of erbium-doped fibers (EDFs) [2]. A great deal of research has been focused on the technique by inserting a filter into the EDF laser cavity for multiwavelength oscillations [4]- [6]. In such arrangements, the cavity losses corresponding to the different wavelengths have to be balanced with the cavity gains simultaneously.…”

Tunable Dual-Wavelength Laser Scheme by Optical-Injection Fabry-Perot Laser Diode

“…Tunable and stable multiwavelength fiber lasers are important and attractive in recent years because of their potential applications in wavelength-division-multiplexed (WDM) technique (Das et al, 2002;Slavik et al, 2002), optical code-division multiple-access (OCDMA) technique (Barmenkov et al, 2008;Alvarez-Chavez et al, 2007), fiber sensor system (Chou et al, 2008;, and optical instrument measuring (Talaverano et al, 2001;Nilsson et al, 1996) and testing (Liu et al, 2004;Li et al, 1998). Different techniques for the reduction of wavelength competition have been used to achieve stable multiwavelength oscillations.…”

Fiber Optical Parametric Oscillator With Switchable and Wavelength-Spacing Tunable Multi-Wavelength

“…So far, several FOPOs including continuous-wave (cw) and pulsed FOPOs have been demonstrated [10][11][12][13][14], which, however, have only a singlewavelength oscillation. Multi-wavelength fiber lasers (MWFLs) have received considerable attention for their potentials in applications such as wavelength-division-multiplexing (WDM) communication, optical instrument testing, optical fiber sensors, microwave photonics and spectroscopy [15][16][17][18].…”
