Fourier or spectral domain optical coherence tomography (FDOCT) is a multi-dimensional interferometric imaging modality that has attracted increasing interest during the last few years. The reason is its outstanding sensitivity allowing high speed 2D and 3 ...
We show that the spectral broadening of the pump pulse through self-phase modulation in a time-domain distributed Brillouin sensor has a considerably detrimental effect in the measurement, especially in the case of long distances and high-resolution pulses ...
Brillouin scattering is particularly efficient and attractive for the implementation of strain and temperature distributed sensing in optical fibres. Recently a trend has been observed that modern advanced applications require a substantial step towards be ...
We present a holographic recording technique with 150 femtosecond time resolution. This technique allows us to capture either a single hologram with fine spatial resolution (4μm), or a time-sequence of multiple holograms with reduced spatial resolution in ...
We are fabricating a bulk-micromachined micromirror device for laser pulse shaping applications on femtosecond time scales. An array of micromirrors is used to individually retard or diminish certain laser frequencies spanning from the UV to the near-infra ...
Dynamic control of the speed of a light signal, based on stimulated Brillouin scattering in optical fibers, was theoretically studied and also experimentally demonstrated as the core object of this thesis. To date, slow light based on stimulated Brillouin ...
We have implemented a holographic system to study the propagation of femtosecond laser pulses with high temporal (150 fs) and spatial resolutions (4 μm). The phase information in the holograms allows us to reconstruct both positive and negative index chang ...
We report an experimental demonstration of optical parametric generation in a periodically poled KTiOP O4 crystal based on the principle of mirrorless optical parametric oscillation. A femtosecond pump pulse spectrally centered at 792 nm from a Ti:sapphire ...
We describe a holographic technique capable of sampling dynamic events at 150 femtosecond time resolution. We apply the technique to the study of the nonlinear propagation of high energy pulses through gas and condensed media. The holograms are recorded as ...
We present an RF-driven two-stage 40 GHz RZ pulse source based on self-phase modulation and a fiber optic parametric amplifier, for generation of 1.1 ps pulses, and demonstrate generation of OTDM data up to 320 Gb/s. ...
