چکیده
Tunable multiwavelength fiber lasers based on semiconductor optical amplifiers (SOA) have received attracting interest due to their wide prospective applications in dense division multiplexing (DWDM) systems and sensing. Using an SOA a nonlinear loop mirror (NOLM), we demonstrate up 13 lasing peaks by controlling the pump current polarization controller. At maximum (450 mA), emitted is between 1550 nm 1572 with wavelength spacing of 1.87 3 dB output linewidth 0.8 power −7 dBm 27 signal-to-noise ratio (OSNR). The peak stability are investigated, it was found that fluctuation each line less than 0.2 dB. In addition, adjusting controllers (PCs) temperature, obtained tunable emission. proposed laser offers advantages such as simple structure, low loss, long-time stable

Tunable multiwavelength SOA fiber laser with ultra-narrow wavelength spacing based on nonlinear polarization rotation.
A tunable multiwavelength fiber laser with ultra-narrow wavelength spacing and large wavelength number using a semiconductor optical amplifier (SOA) has been demonstrated. Intensity-dependent transmission induced by nonlinear polarization rotation in the SOA accounts for stable multiwavelength operation with wavelength spacing less than the homogenous broadening linewidth of the SOA. Stable mul...

A SOA-based multiwavelength fiber ring laser for fiber sensing network is introduced in the paper. According to the demand of our sensing network which is a six-channel WDM system, the output wavelength of our MFRL is in the band of 1537nm to 1547nm with a frequency space of 200GHz. In the experiments, stable output and good flatness are acquired. Factors that can influence the wavelength shift...

We have demonstrated the application of a multiwavelength fiber ring laser as a cost-effective light source for wavelength-division-multiplexed passive optical networks for the first time. The performances of the system for downstream signal are experimentally investigated. We have achieved error-free transmission over 17 km of dispersion-shifted fiber at a bit rate of 1.25 Gb/s per channel.
متن کاملTunable multiwavelength fiber laser using a comb filter based on erbium-ytterbium co-doped polarization maintaining fiber loop mirror.
A tunable comb filter based on a fiber loop mirror setup, which incorporates a piece of pumped erbium-ytterbium co-doped polarization maintaining fiber, is newly presented. It is accomplished by controlling the pump power or adjusting a polarization controller in the loop mirror, which results from the fact that the effective birefringence of the erbium-ytterbium co-doped polarization maintaini...

A tunable and switchable multiwavelength erbium-doped fiber ring laser based on what we believe to be a new type of tunable comb filter is proposed and demonstrated. By adjusting the polarization controllers, the dual-function operation of the channel-spacing tunability and the wavelength switching (interleaving) can be readily achieved. Up to 29 stable lasing lines with 0.4 nm spacing and 14 l...
