A stable 40 GHz-spacing optical-combs are generated using a single supercontinuum source pumped by an optically multiplexed 40 GHz, 2-ps mode-locked semiconductor laser diode. A distribution over the 80 km WDM fiber link of more than 80 lines of 40 GHz-spacing optical-comb ranged from 1533 nm to 1610 nm, which cover the C-and L-band in the WDM optical fiber networks, are experimentally demonstrated.
A repetition-rate-stabilized frequency comb ranging from the violet to the mid-infrared is obtained by phase-locking a femtosecond Ti: sapphire laser and synchronously pumped optical parametric oscillator to a common supercontinuum reference.
An effective supercontinuum generation is demonstrated by injecting picosecond self Q-switched mode-locked Nd:GdVO4 laser pulses into an 1 m long microstructured fiber (MF) near the longer zero-dispersion wavelength of the dual zero-dispersion points

By using a recently developed nonlinear fiber, we achieve octave-spanning spectrum directly from a diode-pumped passively mode-locked 250-fs Er:Yb:glass laser without any amplification stage. Applications for CEO phase stabilization and optical clocking are discussed.
This presentation gives an emphasis on the development of all-fiber chirped pulse amplifier (CPA) sources. It describes both Yb and Yb-Er based CPAs, where powers of 20 kW in picosecond pulses recompressed in up to 110 m of air core photonic band gap fibre. The problem of dispersion slope, leading to incomplete recompression of the stretched pulses are also described, as well as the simple compression...
We demonstrate a flat supercontinuum generation over 185 nm in a dispersion-flattened nonlinear photonic crystal fiber working in the normal dispersion regime only, with all-fiber configuration and only 10 mW mode-locked pump pulses
We report on the generation of an ultrabroad supercontinuum spanning from 400 nm to over 1750 nm in an extruded SF6 PCF with only 200 pJ pulses from an all-fiber Er laser-amplifier system.
