We propose and experimentally demonstrate a continuous wave (CW) tunable-wavelength fiber laser using self-seeding Fabry-Perot laser diode (FP-LD) without optical amplifier inside gain cavity. By employing a tunable bandpass filter (TBF) and a fiber reflected mirror (FRM) within a gain cavity, the fiber laser can lase a single-longitudinal wavelength due to the self-seeding operation. The propo...

The demand for optical networks with a high bit rate at a long transmission distance is growing at yearly basis [1,2]. The signal transmission in optical networks experiences propagation attenuations along a long span of optical fiber links, which in units of dB/km is defined by (10 / ) log( / ) α = − o in L P P , where in P is the input power to the fiber and o P denotes the output power at th...

We demonstrate self-referencing of a Tm-doped fiber oscillator-amplifier system by performing octave-spanning supercontinuum generation in a periodically poled lithium niobate waveguide. We model the supercontinuum generation numerically and show good agreement with the experiment.

For the first time, a 2-micron master-oscillator-power-amplifier laser using a fiber based phase conjugation mirror has been demonstrated. The beam quality improvement and 56% of the PCM reflectivity have been achieved.

We propose and demonstrate a polarization independent Raman-assisted fiber optical parametric amplifier using depolarized Raman and parametric pumps. The polarization dependent gain fluctuation has been reduced from >10 dB to less than 1 dB.

A new tunable fiber ring laser structure employing an Opto-VLSI processor and an erbium-doped fiber amplifier (EDFA) is reported. The Opto-VLSI processor is able to dynamically select and couple a waveband from the gain spectrum of the EDFA into a fiber ring, leading to a narrow-linewidth high-quality tunable laser output. Experimental results demonstrate a tunable fiber laser of linewidth 0.05...

We demonstrate that appropriately designed doped multimode fibers provide robust single-mode output when used within a fiber laser cavity. Using a novel large-mode-area fiber, we demonstrate what we believe to be record single-mode (M(2) <1.2) pulse energies of >0.5 mJ from a Q -switched fiber laser and even higher pulse energies (as high as 0.85 mJ) with slightly compromised spatial-mode quali...

36 LLE Review, Volume 97 Fiber laser and amplifier development in the wavelength region near 1 μm has experienced significant progress owing to the exceptional efficiency and gain bandwidth of ytterbiumdoped fibers.1–5 In fact, both ytterbium fiber lasers and amplifiers are becoming more attractive than their bulk counterparts due to their confined spatial mode, impressive bandwidth, good pump ...

We use the variational method to find the optimum launch conditions that can sustain path-averaged solitons in a periodically amplified, constant-dispersion, optical communication system even when amplifier spacing is comparable to or larger than the dispersion length. We determine the amount of prechirping and the initial peak power required and show that both the pulse width and the chirp rec...
