Abstract

We show, by using numerical simulations, that quasisolitons can propagate over a long distance in a fiber Bragg grating that is written in a slow saturable fiber amplifier, such as an erbium-doped fiber amplifier. During the pulse propagation, the front end of the pulse experiences a net gain while the rear end of pulse is attenuated due to the combination of gain saturation and loss. However, the pulse profile almost does not change after propagating over a length of 5 m that is approximately 2500 times larger than the spatial pulse width. The pulse amplitude has an approximately hyperbolic secant profile. We develop a reduced model by using a multiscale analysis to study solitary-wave propagation when nonlinearity and gain are small. When gain saturation also becomes small we find analytically a new family of solitary-wave hyperbolic-secant solutions that approximately solve the reduced model. The solitary waves propagate slightly faster than Bragg solitons that propagate in fiber Bragg gratings without gain and loss.

Behavior of Bragg gratings, written in germanosilicate fibers, against [gamma]-ray exposure at low dose rate

Journal Article Niay, P ; Bernage, P ; Douay, M ; ... - IEEE Photonics Technology Letters (Institute of Electrical and Electronics Engineers); (United States)

Bragg gratings have been written within four germanosilicate fibers either by a pulsed or by a continuous-wave exposure of each fiber to a coherent UV two-beam interference pattern. These gratings have been exposed under steady state conditions to [gamma]-ray doses as high as 10[sup 4] Grays. The dose rates ranged between 10 Gy/h and 1.3 [times] 10[sup 2] Gy/h. The transmission spectra of the fibers have been recorded during and after the [sup 60]Co irradiation, near the grating Bragg wavelengths. Whereas the induced loss reached 600 dB/km near 1.3 [mu]m, no significant change in the spectral characteristics of the gratingsmore »« less

Generation of self-induced-transparency gap solitons by modulational instability in uniformly doped fiber Bragg gratings

Journal Article Kalithasan, B ; Porsezian, K ; Senthilnathan, K ; ... - Physical Review. A

We consider the continuous-wave (cw) propagation through a fiber Bragg grating that is uniformly doped with two-level resonant atoms. Wave propagation is governed by a system of nonlinear coupled-mode Maxwell-Bloch (NLCM-MB) equations. We identify modulational instability (MI) conditions required for the generation of ultrashort pulses in both anomalous and normal dispersion regimes. From a detailed linear stability analysis, we find that the atomic detuning frequency has a strong influence on the MI. That is, the atomic detuning frequency induces nonconventional MI sidebands at the photonic band gap (PBG) edges and near the PBG edges. Especially in the normal dispersion regime,more »« less

Environmentally stable high-power soliton fiber lasers that use chirped fiber Bragg gratings

Journal Article Fermann, M E ; Sugden, K ; Bennion, I - Optics Letters

Environmentally stable high-power erbium fiber soliton lasers are constructed by Kerr or carrier-type mode locking. We obtain high-energy pulses by using relatively short fiber lengths and providing large amounts of negative dispersion with chirped fiber Bragg gratings. The pulse energies and widths generated with both types of soliton laser are found to scale with the square root of the cavity dispersion. Kerr mode locking requires pulses with an approximately three times higher nonlinear phase shift in the cavity than carrier mode locking, which leads to the generation of slightly shorter pulses with as much as seven times higher pulse energiesmore »« less

Hybrid diode-laser fiber-amplifier source of high-energy ultrashort pulses

Journal Article Galvanauskas, A ; Fermann, M E ; Blixt, P ; ... - Optics Letters; (United States)

We demonstrate what we believe is the first compact laser system for generating ultrashort microjoule-energy optical pulses. Linearly chirped pulses from monolithic tunable Bragg-reflection laser diodes were amplified in a diode-pumped two-stage erbium-doped fiber amplifier and compressed with a grating-pair compressor. The laser diodes had their emission wavelengths at 1.538 and 1.562 [mu]m. The highest pulse energies obtained were 2 [mu]J at the repetition frequencies of 1--10 kHz and were at the saturation energy level of the fiber amplifier. The shortest duration of compressed pulses is 1.8 ps.

High-power soliton fiber laser based on pulse width control with chirped fiber Bragg gratings

Journal Article Fermann, M E ; Sugden, K ; Bennion, I - Optics Letters

Chirped fiber Bragg gratings control the pulse width and energy in Kerr mode-locked erbium fiber soliton lasers. We create high-energy pulses by providing large amounts of excessive negative dispersion, which increases the pulse width while keeping the nonlinearity of the cavity constant. With a chirped fiber grating of 3.4-ps{sup 2} dispersion, 3-ps pulses with an energy content higher than 1 nJ are generated at a repetition rate of 27 MHz. By controlling the polarization state in the cavity, we obtain a tuning range from 1.550 to 1.562 {mu}m.
