Soft-glass photonic-crystal fiber is used to generate broad supercontinuum using an all-fiber-femtosecond laser. The bandwidth exceeds 1700 nm and has average powers in excess of 100 mW with 46-MHz repetition rate.
We demonstrate efficient compression of low-power 6 ps pulses down to 420 fs pedestal free pulses at 1.5 mum in an all-fiber scheme employing only 4 meters of As2Se3 fiber and a tailored chirped fiber Bragg grating.
Fiber-delivered laser source provides the flexibility desired for optical imaging systems. Here we demonstrate laser-scanning coherent anti-Stokes Raman scattering imaging with two picosecond laser sources delivered by large mode area photonic crystal fiber.
All-fiber chirped-pulse amplification based on a large-mode-area Er:Yb-doped photonic-crystal fiber is presented. A dispersion-variable hybrid fiber stretcher compensates the peculiar dispersion of the hollow-core photonic-bandgap fiber compressor yielding transform-limited 440-fs pulses with 1-W average power.
We report on an Ytterbium gain band, holey fiber based modulation instability laser. The all fiber integrated source produces a 40 GHz train of 4 ps pulses at a wavelength of 1064 nm.
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 propose and demonstrate super-continuum generation from 1-mum ASE noise source instead of ultra-short pulses for the first time. With the amplified noise burst, super-continuum is generated over 500 nm with 23 dBm average power.
A new technique to control the chromatic dispersion of a uniform fiber Bragg grating based on the symmetrical bending for the tunable pulse repetition-rate multiplication is proposed and experimentally demonstrated.
We study the correlation in the shifted key induced by the dead time of Geiger-mode avalanche photodiodes (APDs) in quantum cryptographic systems. A simultaneous hold-off of the APDs (SHA) technique eliminates these correlations.
Parabolic pulses from a similariton amplifier at 1550 nm are compressed using optimized linear compression in photonic bandgap fiber and soliton effect compression in dispersion-flattened highly nonlinear fiber. Transform-limited 20 fs pulses are obtained.
We report on the excellent agreement of a first-principles, quantum dynamical simulation with the experimentally measured results of a fiber squeezer using intense, ultra-short laser pulses.
We demonstrate picosecond-pulse transmission over 20 Mm using an all-optical 3R regenerator cascaded 200 times. Bit-error rate curves and cross-correlations show good pulse quality and a 1-dB penalty compared to back-to-back.
We experimentally demonstrate a novel Kerr shutter functioned by the interaction of carbon nanotubes with the evanescent-field of propagating light in a D-shaped fiber. The scheme initiates applications of the nanotubes to ultrafast all-optical switches.
