In the pulse application, a significantly increased efficiency of high power largemode area fiber amplifiers is demonstrated by improving the overlap of the doped region with the fundamental mode of the fiber.
Heating a photo-darkened ytterbium fiber causes a recovery in spectral transmission to the pre-darkened state. Exposure to H2 at high temperatures causes a permanent change in the visible transmission identical to that caused by photo-darkening.
We report a high power diode-pumped mid-IR fiber amplifier at 2.7 mum. 4.6 W amplified signal was obtained for an input signal of 110 mW, corresponding to a net gain of 16.2 dB.
We have derived an explicit analytical expression for the gain of a Brillouin fiber amplifier operating in the depleted pump regime. The accuracy of the obtained formula is validated both numerically and experimentally.
Employing all-optical means to prepare phase-coherent input signal-idler pairs, we implement a multichannel in-line phase-sensitive fiber-parametric amplifier. Feasibility of three-channel operation using a single pump is demonstrated.
Benefits provided by a new high-power and low-noise laser for efficient first-order Raman co-pumping are experimentally investigated. 8 times 10 Gb/s WDM channels have been successfully transmitted over 70dB of standard single-mode fiber with realistic system margins.
Using an accurate full-vectorial finite element method, a realistic model of a fabricated dispersion compensating photonic crystal fiber is analyzed. An almost flat Raman-gain spectrum (gain-ripples at just plusmn0.48-dB) is obtained using a single pump.
We have demonstrated a polarization-interleaved WDM system with a two-orthogonal-pump OPA (2OP-OPA). The sensitivity has been improved by about 2 dB compared to its counterpart with all WDM channels co-polarized with the same signal gain.
Power scalable approach for THz generation is demonstrated using optical rectification in GaP pumped by a high power ultrafast Yb-doped fiber amplifier. 1.8 muW THz radiation is obtained from 2.6 W pump power.
We report using short, heavily-doped active phosphate fiber for generation of picosecond pulses at 1.5 mum, with the peak power of 19 kW which results in a record-high aerial power density of 24 GW/cm2 in the fiber core.
We present a highly non-linear holey fiber with low loss and low OH absorption which enables us to demonstrate efficient Raman amplification in the C band with pump wavelengths of 1453 and 1480 nm.
Frequency modulating the pump laser in SBS slow-light delay systems increases the effective Brillouin bandwidth by nearly two orders of magnitude, making the fiber Brillouin amplifier technique applicable to all-optical controllable delay of Gb/s data.
We introduce the design of an amplifying and nonlinear microstructured optical fiber. This unusual guide permits the nonlinear propagation with regeneration of the pump wave. The first fabricated structure is experimentally tested for supercontinuum generation.
Broadband pulse amplification is demonstrated with a fiber laser pumped high repetition rate optical parametric amplifier. Subsequent pulse compression in a prism sequence resulted in 46 fs pulses with peak powers above 10 MW.
